CHAPTER 1 General Description
1.1 Features
1.2 Drive Configuration
This chapter describes the features and configuration of the optical disk drives.
The MCJ3230SS (hereafter, the optical disk drive) is the successor model to the
MCE3130SS. This optical disk drive, which maintains compatibility with the
MCE3130SS, offers high performance and high capacity. Supporting 2.3 GB of
storage capacity, this device delivers superior performance with a 5,455-rpm
rotational speed, and supports security functions.
The optical disk drive is high-performance, 90 mm (3.5-inch) commutative
rewritable optical disk drive which incorporates an SCSI controller.
The interface connecting the optical disk drive to the host system complies with
the SCSI-2.
The flexibility and expandability through SCSI I/F, the high performance of the
optical disk drive, and the drive's commands set enable the user to construct high-
reliability, high-performance disk subsystems with advanced functions and large-
scale storage.

General Description
1.1 Features
This section describes the following drive features:

•
•
Performance
Reliability
Maintainability/operability
Adaptability
Interface
1.1.1 Performance
(1) Half-height standard 90 mm (3.5-inch) size (25.4 mm height)
The SCSI controller can be connected to the system SCSI bus. The controller
meets the specifications of the standard 25.4 mm height 90 mm
(3.5-inch) fixed disk drive form factor.
(2) 2.3 GB capacity
The optical disk drive conforms to the 2.3 GB GIGAMO standard. It also
supports read and write accesses to 128 MB, 230 MB, 540 MB, 640 MB, and 1.3
GB disks.
(3) High-speed data transfer
The optical disk drive supports a disk media rotational speed of 3,637 rpm when
using 2.3 GB disks. The device supports a rotational speed of 5,455 rpm (ZCAV)
when using a 128 MB, 230 MB, 540 MB, or 640 MB disks. When using 1.3 GB
disks, the optical disk drive supports ZCAV mode with a rotational speed of 3,637
rpm, and ZCLV mode that controls the speed at three levels: 3,637/4, 138/4,801
rpm, in accordance with the position of the optical head.
In ZCLV mode, the optical disk drive speeds up by detecting continuous accessing
of inner disk tracks to prevent a reduction of inner disk rotation.
For random accesses, the optical disk drive switches to ZCAV mode that is fixed
to 3,637 rpm to prevent access performance degradation.
In the disk unit, high-speed data transfers at rates of 4.62 to 8.26 MB/s (2.3 GB)
are realized. The maximum data transfer rate on the SCSI bus is 20 MB/s in
synchronous transfer mode.
The SCSI bus high-speed data transfer capacity can be used effectively through
the optical disk unit's large capacity data buffer.

C156-E224-01EN
1.1 Features
(4) High-speed mean seek time
This drive features a linear voice-coil motor for high-speed head positioning. The
average seek time is the average of 1,000 random seeks and is 19 ms. (However,
this does not include command overhead or address check.)
(5) Compatible with international standards (media interchangeability)
90 mm (3.5 inch) type optical disks as well as ISO standards compatible 128 MB,
230 MB, 540 MB and 640 MB format optical disk media can be used in the optical
disk unit.
(6) Direct-overwrite medium support
The drive can use an optic modulation direct-overwrite disk that does not perform
an erase operation; 230-MB disk, 540-MB disk with the ISO standard.
(7) Dust resistance
The optical disk unit provides low-power consumption, eliminating the need for a
cooling fan. The top of the cartridge is sealed with film, and the bottom of the
optical disk unit is sealed with sheet metal, providing protection that is not
complicated.
The optical disk drive needs class 5 millions or less of the dust particles.
(8) Lower power consumption
The power consumption of the optical disk drive is 6.5 W (These power
consumption values are typical values during read and write operation.) These
drives do not use a fan.
The minimum power consumption is 1.0 W (typical value) during power save.
(9) Automatic spindle stop function
If access is not made within a certain time, this function stops disk rotation to
minimize dust accumulation on the disk. This function can be set that time by the
MODE SELECT command.
1.1.2 Reliability
(1) Mean time between failures (MTBF)
This drive features a 120,000 hour MTBF.
(2) Error recovery
For the error depending on the optical disk drive, recovery process is made by a
suitable retry. This drive features Reed-Solomon error correction (ECC) to assure
error-free operation.
C156-E224-01EN
1-3
General Description
(3) Automatic allocation of alternate data blocks
This drive features a function which automatically allocates alternate data blocks
to defective data blocks detected while data is being read from or written to an
optical disk.
1.1.3 Maintainability/operability
(1) Diagnostic function
This drive has a diagnostic function to check optical disk drive operations. The
diagnostic function facilitates test and restoration.
(2) Five-year service life (no overhaul)
This drive will not require overhaul within the first five years of installation if
appropriately handled, maintained, and cleaned as recommended.
1.1.4 Adaptability
(1) Wide operating environment
An LSI circuits reduce power consumption. This drive features a wide operating
environment (5 to 45°C, general office environment). Dust particles are class 5
millions or less.
(2) Vibration resistance (shock resistance)
Rubber vibration isolators protect the drive against external shock or vibration.

C156-E224-01EN
1.1 Features
1.1.5 Interface
(1) Conformance to SCSI-2
This optical disk device supports the basic functions of SCSI-2.
SCSI commands enable data manipulation using logical block addresses that are
independent of the physical attributes of the optical disk device, enabling software
flexibility in terms of system expansion in the future.
(2) Continuous block processing
Logical block addresses are used for data block addressing. Without consideration
of the physical attributes of track boundaries, the host can access data by
specifying a block number in logically continuous data space.
(3) Data buffer
7,600 KB buffer is used to transfer data between the SCSI bus and disk. Since
data is stored in this buffer, the host can execute input-output processing
effectively by using the high-speed data transfer capability of the SCSI bus
without regard to the data transfer rate of the optical disk drive.
(4) Read-ahead cache feature
The read-ahead cache feature enables high-speed sequential data access as
follows:
After executing a command to read data from the disk, the drive automatically
reads the next data block and stores it in the data buffer (pre-reading). If the next
command requests this data, the data is transferred from the buffer without another
disk access.
(5) Write cache feature
When the host system issues the write command to the optical disk drive, a
command complete is usually responded after completion of the write and verify
operations. By using the write cache feature, a command complete is responded
after completion of the data transfer to the data buffer without waiting the
completion of the write and verify operations then the write and verify operations
are made asynchronously with the interface operation. Therefore, the apparent
write command processing time measured at the host system is reduced and the
I/O performance of the host system is improved.
The write cache feature is enabled or disabled by MODE SELECT command.
C156-E224-01EN
1-5
General Description
When the write cache feature is enabled, a write error is reported at
the completion status of next command. At a system so that the host
retries the command, a retry process may be failed.
(6) Defective block slipping
When a disk is initialized, logical data blocks are reallocated in a physical
sequence by slipping defective data blocks. This enables high-speed continuous
data block processing without rotational delay due to defective data blocks.
(7) Device driver software
The optical disk drive requires more extended processing time than conventional
optical device drives because of higher density. Consequently, a processing time
timeout when using the OS can occur and this requires special device driver
software.

General Description
1.2.2 Configuration
Figure 1.3 shows the drive configuration.
The drive consists of mechanical sections, a fixed optics section, actuator, and a
control circuit section. The mechanical sections include the spindle motor,
actuator section, bias magnet, and the cartridge folder vertical motion mechanism.
The fixed optics section consists of the optical components, position detector, and
LD controller.
The control circuit sections include the drive control circuit section and SCSI
controller section.

1.2 Drive Configuration
1.2.3 Mechanical sections
(1) Optical disk cartridge load/eject
The system includes a cartridge mechanism which lowers the optical disk cartridge
and mounts (loads) it on the spindle motor automatically when the optical disk
cartridge is fully inserted in the optical disk drive's disk slot, and a mechanism
which automatically ejects the cartridge when the Eject button on the front panel is
pressed.
(2) Spindle motor
Optical disk cartridge hubs are linked through magnetic clamps to minimize
slippage between the spindle motor shaft and disk. The spindle motor is the direct
drive type which rotates the disk at the same speed as the spindle motor shaft. A
DC brushless spindle motor is used. The spindle motor rotates at 5,455 rpm
0.1%.
(3) Actuator section
The positioner moves (seeks) a head actuator radically across the disk surface.
The positioner is driven by a linear voice coil motor. A pulse-width modulation
(PWM) is adopted as a driving system and realizes low power consumption and
high-speed access.
(4) Separate optical sections
The optical head section is separated in such a way that the fixed optics section
is separated from the moving optics section to minimize seek time and positioning
error. (See Subsection 1.2.4 for the fixed optical section.) This reduces the weight
of the moving parts.
The fixed optics section consists of the laser diodes, collimator lens, and optical
detector.
The fixed optics section includes a laser diode for recording and playback, and
transmits one laser beam to the head actuator.
(5) Panel
The central part of the panel is hollowed out deeply to provide pushing finger
space for inserting the cartridge, thereby facilitating the insertion.
The panel is also simply designed by making the eject button and LED light
emitting part integral with each other.
C156-E224-01EN
1-9
General Description
1.2.4 Control circuit section
Figure 1.4 is the block diagram of the control circuit section.
Figure 1.4 Control circuit section block diagram
The control circuit section is divided into two parts: a controller section which
deals with control between the SCSI interface and drive interface, and a drive
circuit section which controls the drive.
(1) Controller circuit section
The controller circuit's reliability is improved by large-scale integrated circuit
technology. The high-speed microprocessor (MPU) handles SCSI interface
control and drive control such as drive read-and-write control and single-beam
control.
(2) Drive circuit section
The drive circuit section consists of the following circuits:
•
•
•
•
•
Laser diode control circuit
Signal reproduction circuit
Servo/seek control circuit
Rotation control circuit
Drive miscellaneous control circuit
1-10
C156-E224-01EN
1.2 Drive Configuration
The DSP (digital signal processor) is used for the servo/seek control circuit to
reduce the circuit amount, therefore this circuit is a simple configuration.
The drive circuit section executes operations such as seek, erase, record, and
playback while the MPU controls the focus-tracking of the beam.

requirements.
3.1 Environmental Requirements
The environment in which these drives are installed must comply with the ambient
environmental requirements defined in Subsection 2.1.3.
3.1.1 Temperature measurement point
When a drive is operating, the ambient temperature measured 3 cm from the base
surface of the optical disk drive and the PCA unit surface must satisfy the
environmental requirements specified in Subsection 2.1.3. For the temperature of
each surface during operation, the contact temperature at each measurement point
shown in Figure 3.1 must satisfy the requirements specified in Subsection 3.1.2.
Low temperature burns: The surface temperatures of some ICs
on the printed circuit board unit in the optical disk drive exceed
55°C while operating. Be careful of low tenperature burns.

* Following procedure is for temperature measurement of inside cartridge.
1) Make a hole for the thermocouple as shown in Figure 3.1.
2) Disassemble the cartridge disk.
3) Cut off a part of the partition wall for the optical media as shown in Figure
3.1. (Cut off width: 5 to 10 mm)
4) Fix the tip of the thermocouple to the cut portion of partition wall with an
adhesive agent.
5) Pass the thermocouple through the hole at the cartridge case and assemble the
cartridge disk. When there is a gap between the hole and the thermocouple,
fill the gap with the adhesive agent.
Note:
The surface of the cartridge shown in Figure 3.1 has been cut away to make
the elements inside the case clearly visible. In reality the surface is not cut
away.
If the external environment temperature is higher than the specified value, the
device will automatically take an interval to respond to command, and then
take protective action to respond to the temperature increase.
3.1.3 Air flow
It is recommended that this optical disk drive be installed in a fanless cabinet.
However, if the power supply is incorporated into the same cabinet, it is necessary
that it satisfy the "Temperature Conditions" in 3.1.2 and that the air flow rate
being drawn in by the device) at the cartridge loading slot be 0.3 m/s or lower.
Furthermore, if there is a system fan in a system where this drive is being installed,
the same conditions must be met.

Notes:
1. The above data are data estimated as they were measured where the
temperature surrounding the equipment was kept at 45 °C, using that at
25 °C. They are not the same as the data obtained from measurements
using the exclusive box in which the equipment is normally used.
2. When using the box, the ambient temperature around the equipment will
differ depending on the air circulation conditions of the box, and the
temperature rise inside the cartridge will differ because of this, so please
exercise caution.
3.1.5 Air purity
Air purity in the device environment is expressed by the number of dust particles
per unit area and must be class 5 millions (equivalent to 0.15 mg/m3) or less.

3.2 Mounting Requirements
3.2.4 Notes on mounting
(1) Mounting frame structure and clearance
a) For vibration resistance and heat dissipation, this optical disk drive uses an
embossed structure as shown in Figure 3.6, as well as a frame which has a
construction similar to other frames which perform the same function.
b) As shown in Figure 3.6, the inward projection of the mounting screw from the
outer surface of the drive frame must not exceed 3 mm.
c) The clearance between the external surface of the drive frame and the user's
frame structure must be at least 1.5 mm.
d) The clearance between the top and bottom surfaces and the user's frame
structure must be at least 1.5 mm.
e) When mounting the optical disk drive, the screw tightening torque should be
0.4 to 0.45Nm (4 to 4.6kgcm).
f) When the optical disk drive (with panel) is mounted in a locker, there should
be no deformation of the mounting fittings provided and the optical disk
drive's panel should not be deformed. If the drive is used with the panel
deformed, ejection of the cartridge will be faulty. Check if the door will close
from any position whatever when the optical disk drive is installed.

(4) External magnetic fields
Mount the optical disk drive away from powerful magnetic materials (e.g., a
speaker) to avoid influence from magnetic fields.
(5) Leak magnetic field
The VCM drive magnetic circuit may leak the magnetic field (Maximum 25 mT at
distance of 4 mm from the drive).
Do not place a device sensitive to a magnetic field near the optical
disk drive.
(6) External light source
Mount the optical disk drive away from strong light sources (e.g., camera flash).
3-10
C156-E224-01EN
3.3 Power Supply Requirements
(7) System ground
The optical disk drive should be grounded to the signal ground (SG) of the power
supply of the system. This SG line should be supplied with the system.
The Frame Ground is shorted in the optical disk drive by a metal strip attached to
the vibration isolation rubber between the frame (FG) and the base (SG).
When mounting the optical disk drive in the Device Bay 120mm (5
inch) of the PC chassis, there are two ways of choosing frames the
metal frame and the plastic (nonconductive material) frame.
When using a plastic frame, there is not a short circuit between FG
of PC and FG of the optical disk drive. As a result, the static
electricity tolerance decreases compared with metal frame.
It is recommended to use a metal frame to enhance the static
electricity prevention.
3.3 Power Supply Requirements
(1) Allowable input voltage and current
The DC power supply input voltage measured at the power supply connector pin
of the optical disk drive (receiving end) must satisfy the requirements in Section
2.1.3.
(2) Current waveform (reference)

3.6 Notes on Drive Handling
3.6 Notes on Drive Handling
(1) General notes
Note the following points to maintain drive performance and reliability:
Device damage:
1) Shock or vibration applied to the drive that exceeds the values
defined in the standard damage the drive. Use care when
unpacking.
2) Do not leave the drive in dirty or contaminated environments.
3) Since static discharge may destroy the CMOS devices in the
drive, pay attention to the following points after unpacking:
-
Use an antistatic mat and wrist strap when handling the
drive.
-
Hold the mounting frame when handling the drive. Do
not touch the Printed circuit board except when setting the
switches.
4) When handling the drive, hold both sides of the mounting
frame. When touching other than both sides of the mounting
frame, avoid putting force.
5) Do not forcibly push up the end of the header pin of the printed
circuit board unit when handling or setting the drive.
(2) Unpacking
•
Make sure that the UP label on the package is pointing upward and start
unpacking on a level surface. Handle the drive on a soft surface such as a
rubber mat, not on a hard surface such as a desk.
•
•
Use care to avoid exerting excessive pressure on the unit when removing the
cushions.
Use care to avoid exerting excessive pressure on the printed circuit board
surface and interface connectors when removing the drive from the antistatic
bag.
•
If the temperature difference between installation locations is 10 degrees or
more, leave the drive in the new location for at least two hours before
unpackaging it.
C156-E224-01EN
3-21
Installation Requirements
(3) Installation
•
Do not connect or disconnect the connectors or change the terminal settings
when the power is on.
•
•
Do not move the drive with the power on.
Eject the optical disk cartridge, lock the carriage securing the head, turn off
the power, then move the drive.
Device damage: Be sure to turn on the power supply before
inserting your cartridge for the first time. It releases the device from
transport protection and enables you to insert the cartridge.
The device may be damaged if you insert the cartridge without
releasing the protection. From the next time, you don't need to turn
on the power supply beforehand.
Before moving the drive, remove the optical disk cartridge. If the
drive is moved with the optical disk cartridge loaded in it, the head
may move back and forth in the drive to damage the head or disk
and reading the data may fail.
(4) Packing
•
•
•
Before packing, remove the optical cartridge.
Store the drive in an antistatic plastic bag with desiccant (silica gel).
Use the same cushions and packaging supplied with the drive. If they are not
available, ensure that adequate shock absorbent material is used. In this case,
some method of protecting the printed circuit board surface and interface
connectors must be used.
•
Apply "UP" and "Handle With Care" labels to the outside of the package.
Figure 3.15 shows the single-unit packing style and the multiple-unit packing
style. (The form and material of the cushion may be changed.)

3.7 Mounting
3.7.1 Checks before mounting the drive
Before mounting the optical disk drive in the system cabinet, check whether the
jumper settings are set correctly.
3.7.2 Mounting procedure
How the drive is mounted depends on the system cabinet structure. Determine the
mounting procedure in consideration of the requirements of each system. This
section contains the general mounting procedure and check items.
See Section 3.2 for details on mounting drive.
1) Tighten four mounting screws to secure the drive in the system cabinet.
−
The drive has ten mounting holes (both sides: 3 × 2, bottom: 4). Secure
the drive using the four mounting holes on both sides or the bottom.
−
Use mounting screws whose lengths are 3 mm or less from the external
wall of the mounting frame of the drive when they are tightened. (See
Figure 3.6)
−
−
When mounting with screws, the screw tightening torque should be 0.4 to
0.45Nm (4 to 4.6kgfcm).
Be careful not to damage the parts on the PCA when mounting the drive.
2) After securing the drive, make sure that the drive does not touch the chassis of
the system cabinet. There must be at least 1.5 mm clearance between the
drive and chassis. (See Figure 3.6)
3-24
C156-E224-01EN
3.8 Cable Connections
3.8 Cable Connections
Use the following cables to connect the drive to the system. See Subsection 3.4
for details on the connector positions and cable requirements.
•
•
•
Power supply cable
SCSI interface cable
DC ground cable (if required)
The general procedure for cable connection and notes on connecting cables are
given below. Pay attention to the insertion direction of each cable connector.
•
•
Make sure that the system power is off.
Do not connect or disconnect any cable when the power is on.
1) Connect the DC ground cable (only if required to decrease ground noise).
2) Connect the power cables.
3) Connect the SCSI interface cable.
4) After each cable connector is connected, secure the cable so that the cable
does not touch the drive or the parts on the PCA or obstruct the flow of
cooling air in the system cabinet.

Installation Requirements
3.9 Operation Confirmation and Preparation for Use after
Installation
3.9.1 Confirming initial operations
This section provides the operation check procedures after the power is turned on.
(1) Initial operation when the power is turned on
•
•
•
When the power is turned on, the drive starts initial self-diagnosis. The LED
on the front panel is on for 1 second during initial self-diagnosis.
If an error is detected during initial self-diagnosis, the LED on the front panel
blinks.
In case of not inserted the cartridge, when the power is turned on, the eject
motor automatically turns once.
(2) Checks if errors occur at initial self-diagnosis
•
•
Make sure that the cables are connected correctly.
Make sure that the supply voltage is correct. (Measure the voltage at the
power supply connector of the optical drive.)
•
•
Make sure that the settings of all terminals are correct.
If the LED on the front panel blinks continuously, an error was detected
during initial self-diagnosis. In this case, issue the REQUEST SENSE
command from the initiator (host system) to obtain sense data for error
analysis.
The BUSY LED is on while the optical disk drive is executing seek,
write, or read operations. The BUSY LED is on momentarily, so it
seems as if it blinked or is off.
The eject motor turns once when the power is turned on so that in
case the spindle motor position deviates due to shocks received by
the drive during transport the position is corrected to allow the
cartridge to be inserted normally. If the cartridge fails to be inserted,
remove the cartridge and turn on the drive power to turn the eject
motor once and reinsert the cartridge.
3-26
C156-E224-01EN
3.10 Dismounting Drive
3.9.2 Connection check
When initial operation check terminates normally after the power is turned on,
check whether the drive is correctly connected by issuing command from the host
system. Checking procedure depends on the host system configuration.
If processing terminates abnormally:
1) If sense data has been obtained by the REQUEST SENSE command, analyze
the sense data. If the error is recoverable, retry the processing.
2) Check the following items for SCSI interface cable connection:
−
−
All connectors, including other devices, are connected correctly.
Make sure the correct cable is being used (whether it corresponds with
the cable selection mode).
3) Make sure again that the jumper settings are correct.
3.10 Dismounting Drive
How to demount an optical disk drive (for setting terminal checking, setting
change, or device replacement) depends on the system cabinet configuration.
Determine the demounting procedure in consideration of the requirements of each
system. This section describes the general demounting procedure and notes on
demounting drives.
Device damage: Before demounting the optical disk drive, turn
off the system power. Do not remove screws securing the cables
and drive when the power is on.
1) Remove the power cable.
2) Remove the SCSI interface cable.
3) Remove the DC ground cable.
4) Remove the four screws securing the drive, then remove the drive from the
system cabinet.
5) When storing or transporting the drive, put the drive into an antistatic bag.

4.2 Various Processes
4.2.1 Reset response
Three types of reset responses are available.
•
•
Power-On Reset
The ODD performs initialization processes such as initial diagnosis and
-
default setting. It also starts rotation of the media, if any is mounted.
SCSI Reset
-
-
The ODD is reset when the RESET- signal is asserted. The ODD
performs initialization of the interface controller, including such
operations as writing the default values to the registers.
UNIT ATTENTION is generated.
•
Bus Device Reset
-
The ODD is reset when a bus device reset message is received. The
ODD performs initialization of the interface controller, including such
operations as writing the default values to the registers.
-
UNIT ATTENTION is generated.
4.2.2 Defective sector management
The following standards for each type of media are used to manage sector
mapping:
-
-
-
-
-
ISO/IEC 10090 for 128-MB media
ISO/IEC 13963 for 230-MB media
ISO/IEC 15041 for 540/640-MB media
Cherry Book for 1.3-GB media
Cherry Book 2 for 2.3-GB media
In principle, the initiator need not manage defective sectors.
4.2.3 Automatic alternate sector assignment function
If a verify error is detected in the ID or data section when the WRITE (6/10),
WRITE AND VERIFY, or ERASE command is executed, the ODD automatically
assigns an alternate sector. Alternate sector information is entered in the
secondary defect list (SDL) on the media.
No error is reported if automatic alternate sector assignment ends successfully.
4-4
C156-E224-01EN
4.2 Various Processes
4.2.4 Cache function
The ODD supports read cache and MO write cache.
The read cache consists of the read-ahead cache and the LRU cache that reads
write data remaining in the data buffer.
The read-ahead cache enables data transfer at almost the same speed as the
effective transfer speed during continuous read operation without causing delays
resulting from rotation latency. If write and read operations are executed
frequently on a same sector, the LRU cache enables the transfer of data without
mechanical operation.
The MO write cache writes data in batch mode during continuous write operation,
thus reducing the number of positioning operations, which is determined by the
buffer size, and improving write throughput.
4.2.4.1 Data buffer
The ODD uses part of the buffer area as work memory for control firmware and
the remaining area for a data buffer. The data buffer consists of multiple segments
and contains multiple segments of write data.
4.2.4.2 Read cache
If the read cache function is enabled, the ODD enables the read-ahead cache and
LRU cache. When a READ command is received while the read cache is enabled,
the ODD reads the specified sector and continues pre-reading the following
sectors. The ODD thus transfers data in the sectors specified by the command
while pre-reading the sectors that follow.
When data in the sector specified by the host is pre-read data, the ODD transfers
the data directly from the buffer without any mechanical operation.
The ODD stops pre-reading under any of the following conditions:
•
•
Read error
Data buffer full (The ODD may restart pre-reading when the buffer is no
longer full.)
•
•
•
Media ejection instruction given with the eject switch
Power-off
The system judges that performance will be improved by stopping the pre-
reading and giving priority to other processing.
If the read cache is enabled, the buffer contains data transferred from the host with
a write command. If a read command is issued for an applicable sector address,
the ODD directly transfers data to the host from the data buffer rather than reading
it from the media. If the cache is hit with a read command, the ODD places and
keeps the data in the hit segment in the highest priority.
The following types of data are not subject to the read cache function:
C156-E224-01EN
4-5
Host Interface
•
•
Data read before power-off
Data stored before media is mounted
All buffer data is discarded when:
•
•
•
•
The power is turned off.
The media is ejected.
A FORMAT UNIT command is received.
The ODD is in standby mode.
Buffer data may be discarded when:
A MODE SELECT command that changes the read conditions is received.
•
4.2.4.3 MO write cache
If the write cache is enabled, the ODD responds to the host with command
completion when data transfer for a WRITE or WRITE AND VERIFY command
(hereafter collectively called a write command) is completed.
The ODD writes data stored in the buffer to the media and proceeds to the next
processing when:
•
•
The eject switch is pressed.
A SYNCHRONIZE CACHE command is received.
When data is contained in the buffer, and if any of the following conditions
occurs, the data in the buffer may not be written to the media correctly:
•
•
The power is turned off.
The media is forcibly ejected (mechanical ejection).
4.2.5 Power management function
The ODD provides a power management function that minimizes power
consumption. A timer is used to implement the function.
4.2.6 Power mode
The ODD supports the power modes listed below. If no media is mounted, the
ODD uses a power mode equivalent to standby mode.
•
•
•
•
Active mode
Pre-idle mode
Idle mode
Standby mode
4-6
C156-E224-01EN
4.2 Various Processes
4.2.6.1 Active mode
In active mode, all circuits are enabled and the time for command processing is
minimized.
4.2.6.2 Pre-idle mode
In pre-idle mode, the read and write circuits are in stopped state. The ODD can
receive a command from the host, but since some circuits are stopped, the
command requires an additional 20 ms to access the media.
The ODD automatically enters pre-idle mode if no command is issued within a
specified time (0.5 s) in active mode. The ODD automatically enters active mode
when it receives a media access command.
4.2.6.3 Idle mode
In idle mode, the servo, and read and write circuits are in stopped state. The ODD
can receive a command from the host, but since some circuits are stopped, the
command requires an additional 1 s (default) to access the media.
If no command is issued within a specified time (180 s) in active mode, the ODD
automatically enters pre-idle mode, then enters idle mode. The ODD
automatically enters active mode when it receives a media access command.
4.2.6.4 Standby mode
In standby mode, the spindle motor stays stopped. The ODD can receive a
command from the host, but since the spindle motor is stopped, the command
requires 5 s (default) for recovery before accessing the media.
If no command is issued within a specified time while the ODD is in active mode
with the standby timer enabled, the ODD automatically enters standby mode. The
ODD automatically enters active mode when it receives an access command.
4.2.6.5 Standby timer
The standby timer counts the elapsed time during which the host issues no
commands.
The standby timer value is programmable with the Power Condition Page of the
MODE SELECT command. The default standby timer value is 32 minutes
(including the transition time to idle mode).

ODD control firmware is stored in flash ROM and can be downloaded from
the host with the WRITE BUFFER command. However, if a problem such
as a power failure occurs during downloading, downloading is interrupted
and the microcodes in the control firmware may be damaged. In such a
case, to download the microcode data again, the ODD starts emergency
download firmware that supports only the WRITE BUFFER command and
other basic commands.

The LED that is blinking because of a write cache write error stops blinking
when the media is ejected.

The ODD returns CHECK CONDITION status only when it fails to return the
INQUIRY data requested by the INQUIRY command.
When the ODD receives an INQUIRY command from INIT while it has a UNIT
ATTENTION condition (before the ODD reports CHECK CONDITION status),
the ODD executes the INQUIRY command but does not clear the UNIT
ATTENTION condition.
The transfer byte length field at CDB byte 4 indicates the number of bytes of
INQUIRY data that INIT can receive with this command. The ODD transfers as
many bytes of data as specified by the transfer byte length or the INQUIRY data
held by the ODD, whichever is smaller. If 0 is specified in the transfer byte length
field, the command ends and no data is transferred.

If the Automatic Write Reallocation Enabled (AWRE) bit is 0, no automatic
alternate block assignment is made by the WRITE (6), WRITE (10), or WRITE
AND VERIFY command. If the AWRE bit is 1, an automatic alternate block
assignment function is enabled.
If the Read Continuous (RC) bit is 0, an error is reported if an uncorrectable data
error is detected in the READ (6) or READ (10) command. If the RC bit is 1, the
command transfers the erroneous data and ends normally even if an uncorrectable
data error is detected.
If the Post Error (PER) bit is 0, the command reports GOOD status if an error is
corrected with the error recovery process. If the PER bit is 1, the command
reports CHECK CONDITION status if an error is corrected with the error recover
process. The Sense Key is then set to RECOVERED ERROR.
RECOVERED ERROR is reported when:

•
Seven or eight error bytes occurring per interleaving are corrected by the ECC
feature during a read operation.
A defective sector is detected and replaced with an alternate sector during a
write operation.
An error occurs in one of four sets of media data during media management
information (DMA) write operation caused by the FORMAT UNIT command
(MEDIUM ERROR is set if an error occurs in two, three, or four sets of four
sets).
If the Disable Correction (DCR) bit is 0, the command corrects any correctable
errors detected in a read command. If the DCR bit is 1, the command does not
correct any correctable errors that are detected.
A value of 3 or fewer cannot be specified for Read Retry Count. If 3 or fewer is
specified, the command processing assumes that 4 is specified and reports
Recovered Error.
The value of Write Retry Count must be 3. If a value other than 3 is specified, the
command processing assumes that 3 is specified and reports Recovered Error.
To ensure media compatibility, the read-write error recovery page must contain
the default values, except when the settings are used for a diagnosis.
The values in the Read-write error recovery page can be saved.

As with the RELEASE command (explained next), the RESERVE command
controls exclusive access to the logical unit (ODD) in a multi-initiator
environment. The ODD is reserved for another SCSI device by the INIT that
issues this command.
Any values specified for CDB bytes 1 to 5 are ignored. However, INIT should
specify 00h for these bytes.
The RESERVE command reserves the entire ODD (logical unit) for a specific
SCSI device. The ODD reserved by this command remains reserved until one of
the following conditions is met:
•
The RELEASE command is issued by the INIT that issued the RESERVE
command.
•
•
•
A BUS DEVICE RESET message is issued by an INIT.
A RESET condition occurs.
The ODD power is turned off and on again.
While an ODD is reserved for a SCSI device, an INIT having no "reservation
authority" for the ODD might issue this command. If so, the command ends with
RESERVATION CONFLICT status.
After ODD reservation is established, any commands, other than the INQUIRY,
REQUEST SENSE, and RELEASE commands, issued by an INIT other than the
SCSI device that reserved the ODD are rejected. The RESERVATION
CONFLICT status is reported to the INIT that issued the command. The
INQUIRY and REQUEST SENSE commands are executed normally even while
the ODD is reserved for another SCSI device. The RELEASE command ends
with GOOD status, but any RELEASE command issued by a SCSI device having
no reservation authority for the applicable ODD is ignored.

Key indicates NO SENSE.
When issuing the REQUEST SENSE command to detect the device status, first
issue the TEST UNIT READY command, then issue the REQUEST SENSE
command.
Allocation Length specifies the length of sense data to be transferred, in bytes. If

Progress Indication
Progress Indication indicates the rate of formatting completion when the
denominator is 65536 (10000h).
INIT should not use the REQUEST SENSE command alone to
check the ODD status. Because the REQUEST SENSE command is
used by INIT to retrieve sense data that is held by the ODD on
various occasions, the contents of the sense data depend on the
results of the command executed previously.
Example: Response when the ODD is in Not Ready state
When INIT issues the TEST UNIT READY command,
the ODD ends processing with Check Condition Status
and responds to the REQUEST SENSE command with
Not Ready Sense Data. When the INIT issues the
INQUIRY command, the ODD responds with Inquiry
Data and ends processing with Good status. If INIT
continuously issues the REQUEST SENSE command,
the ODD responds with No Sense because the previous
command has ended normally and the ODD holds no
sense data.

4.4 SCSI Messages
SCSI messages are used to control the SCSI bus operating sequence. This section
explains how SCSI messages work.
4.4.1 Message formats
There are three types of message formats. In any format, the first byte of each
message is a message code (see Table 4.73).
• 1-byte message:
Only the message code
• 2-byte message:
Message with a message code from 20h to 2Fh. Each 2-
byte message consists of a 1-byte message code and a 1-
byte parameter. (The ODD does not support this type of
messages).
• Extended message: Multiple-byte message with message code 01h. An
extended message code and message length are defined
in each message.

4.4 SCSI Messages
4.4.3 Message functions
This section explains the function of each message. The symbols in the following
explanations have the following meanings:
(I → T): Message that can only be sent from INIT to TARG
(T → I): Message that can only be sent from TARG to INIT
(I ←→ T): Message that can be sent between TARG and INIT in either direction
(1) COMMAND COMPLETE message: 00h (T → I)
The execution of a single command ended and valid status information was
reported to INIT. The function of the message is to report the validity of status
information; the message does not always indicate that the command ended
normally. The command end status is indicated in the status byte transferred in the
STATUS phase before the message is sent. Even if command transfer was not
executed normally (because of such reasons as the occurrence of a parity error in
the SCSI data bus in the MESSAGE OUT or COMMAND phase), TARG always
sends this message after the STATUS phase if TARG reports the status byte to
INIT.
After sending this message normally, TARG shifts to the BUS FREE phase.
TARG assumes that message transmission was completed normally if the ATN
signal is FALSE when the ACK signal changes to FALSE at the completion of the
transfer of this message.
(2) SAVE DATA POINTER message: 02h (T → I)
This message instructs INIT to save the current data pointer.
(3) DISCONNECT message: 04h (T → I)
This message notifies INIT that TARG has temporarily disconnected the SCSI
bus. After sending this message normally, TARG shifts to the BUS FREE phase
to complete disconnection. TARG then continues command processing internally.
It reconnects INIT when TARG needs to continue command execution on the
SCSI bus.
(4) INITIATOR DETECTED ERROR message: 05h (I → T)
This message notifies TARG that INIT detected an error for which TARG can
retry command processing. The cause of the error can be something related to
operation on the SCSI bus or something attributable to INIT internal operation that
is not directly related to operation on the SCSI bus.
(5) ABORT message: 06 (I - > T)
This message instructs TARG to clear the I/O operation being executed by INIT.
Upon receipt of this message, TARG interrupts the current operation and shifts to
the BUS FREE phase. The pending data and status related to the interrupted
operation and sense data hold state are all cleared. This message has no effect on
the operation started by another INIT.
C156-E224-01EN
4-43
Host Interface
(6) MESSAGE REJECT message: 07h (I → T)
The message received most recently is invalid or unsupported.
(7) NO OPERATION message: 08h (I → T)
This message causes no operation.
(8) MESSAGE PARITY ERROR message: 09h (I → T)
This message notifies TARG that a parity error was detected in the last message,
in the last byte received by the INIT.
(9) BUS DEVICE RESET message: 0Ch (I → T)
This message instructs the clearing of all I/O operations (commands) being
executed or stacked in TARG. TARG performs initialization by clearing not only
I/O operations started by the INIT that sends this message but also all INIT I/O
operations.

This message specifies the device addresses (LUN) of devices (logical units) under
TARG control to establish I/O operation paths between INIT and TARG.
a. Bit 6: Disconnect Privilege
If INIT specifies this bit as 1, TARG can execute disconnection. If it specifies 0,
TARG cannot execute disconnection.
b. Bits 2 to 0: LUN
These bits specify a logical unit under TARG control.
c. Message function
After the SELECTION phase, INIT first sends this message to TARG to specify
the logical units to be used for I/O operation. Similarly, after the RESELECTION
phase, TARG first sends this message to INIT to specify the logical units to be
reconnected.

5.3 Optical Disk Cartridge Operation
5.4 Cleaning Optical Disk Cartridge
This chapter describes how to operate and clean the drive and the optical disk
cartridges.
5.1 Operating Optical Disk Drive
The drive has an automatic load function. All the operator must do is to insert the
optical disk cartridge and operate the eject button.
This section explains loading and ejection methods, assuming that the drive is
mounted horizontally. When mounted vertically, the drive is operated in the same
manner as when mounted horizontally.
Figure 5.1 shows the front view of the optical disk drive. For operation, users
should be familiar with the parts in the figure and their function. Loading and
ejection methods are described below.

The following explains the parts and functions of the optical disk drive (the
following numbers correspond to the numbers in Figures 5.1):
1) Disk insertion slot
Use this slot to insert and eject the optical disk cartridge.
2) Eject button & BUSY LED (display lamp)
On this optical disk drive, this is the push button combining the eject button
with the BUSY LED (display lamp) for ejecting the optical disk cartridge (it
lights in green during seeking and during erasing, writing or reading of data).
When ejection is disabled by the SCSI command, the optical disk cartridge
cannot be taken out.
3) Manual eject hole
This hole is used to eject the optical disk cartridge manually at power-off.
Manual ejection may not be possible just after the power is off.

5.1 Operating Optical Disk Drive
5.1.2 Note
To maintain the performance and reliability of the drive, keep the following point
in mind:
•
When the drive is in the busy state, do not eject the optical disk cartridge.
Particularly, do not manually eject the cartridge by force.
•
Be careful sufficiently not to insert the different drive (etc. floppy disk) or
substance, so it is cause of the accident.
5.1.3 Inserting cartridge
Insert the cartridge as explained below. (See figure 5.2)
(1) When the drive power is on:
1) Make sure that no disk cartridge is in the drive.
2) Keep the cartridge shutter surface upward.
3) Insert the cartridge, shutter first, into the disk insertion slot.
4) Push the cartridge into the slot until it completes moving below (a little
further in than the operator panel).
Loading is started when the cartridge is inserted. After several seconds, the
BUSY LED indicator lamp is turned on and immediately turned off to
complete loading.
Notes
1) The cartridge must be completely inserted until the BUSY LED indicator
lamp is lit.
2) If the cartridge is inserted by pushing either left or right side of the
cartridge rear, it may not be inserted completely. Be sure to push the
central part straight into the drive until it is completely inserted.
3) If the BUSY LED indicator lamp does not light when the cartridge is
inserted, once eject the cartridge by pressing the eject/BUSY LED button
and insert it again.
4) If you attempt to insert the cartridge by force, trouble may result in the
drive. In such a case, be sure to once remove the cartridge and check the
insertion direction and the face and back of the cartridge before inserting
it again.
(2) When the drive power is off:
1) Make sure that no optical disk cartridge is in the disk drive.
2) Keep the cartridge shutter surface upward.
3) Insert the cartridge, shutter first, into the disk insertion slot.

further in than the operator panel).
The cartridge remains inserted in the drive. The BUSY LED indicator lamp lights
when the drive power is turned on.
The cartridge remains inserted in the drive. Turning on the drive power starts
loading. (The LED indicator lamp should light.)
Notes
1) If the BUSY LED indicator lamp does not light when the power is turned
on, once eject the cartridge by pressing the eject button and insert it again
until the lamp is lit.
2) If the cartridge is inserted by pushing either left or right side of the
cartridge rear, it may not be inserted completely. Be sure to push the
central part straight into the drive until it is completely inserted.
3) If you attempt to insert the cartridge by force, trouble may result in the
drive. In such a case, be sure to once remove the cartridge and check the
insertion direction and the face and back of the cartridge before inserting
it again.
