8. Function of PCA and PMA area  
1) PCA (Power Calibration Area)  
• PCA area is used to determine the correct Laser Power for a disc.  
– Method 1 : PCA area is divided by a track.  
– Method 2 : The previous Calibration value is referred.  
– Method 3 : ROPC is used to determine Laser Power value automatically in data writing.  
• CD-R Disc can write maximum 99 Tracks but CD-RW Disc can write unlimited tracks because it has a rewritable  
function.  
2) PMA (Program Memory Area)  
• It has a track information (track No, track Start/End time) of every track before writing completed.  
– PMA area has the last written point and the next writable point of a disc.  
– In case of CD to CD copy, some writer may not write PMA area.  
* When Disc is Finalized,  
PMA information is transferred to the Lead_In area so that general Driver can read it.  
* Because PCA and PMA area exist before Lead-In area, General CD Player or CD-ROM Drive can’t read  
these areas.  
9. OPC and ROPC  
1) OPC (Optimum Power Control)  
• This is the first step of writing process, because CD writer has its own laser power value and media have different  
writing characteristics,  
– This is determined by the Writing characteristic, speed, temperature, and humidity.  
– Laser wavelength is determined by the environmental temperature (775~795nm) and Optical Laser Power is  
determined by the test and retry.  
• Asymmetry and optimum writing Power  
– EFM signal Asymmetry is determined by the writing power.  
Therefore, Optical Power which has the same value to the preset power value can be estimated by measuring  
HF signal Asymmetry on the PCA area.  
• Measurement of Asymmetry  
* Parameter setting (Beta) : Using AC coupled HF signal before equalization  
Beta = (A1+A2)/(A1-A2)

2) ROPC (Running Optimum Power Control)  
• Variable primary factor of Optimum Power  
– Change of Power sensitivity on the Disc. (limited to 0.05 *Po)  
– Wavelength shift of the laser diode due to the operating temperature change.  
– Change of the Spot aberration due to the Disc skew,  
Substrate thickness, Defocus.  
Incident recording pulse  
– Change of Disc or Optics conditions due to the long term OPC  
==> It is necessary to adjust continuously to obtain the Optimum Power.  
Sampled timing B  
• Principle of Running OPC  
– To meet the factors mentioned above,  
a horizontal _ direction movement of a curve is uesd.  
– Beta = f(B-level) = constant on the Recorded Disc  
– Procedure of ROPC  
a. Reference B-level is determined during OPC Procedure.  
b. During Recording, B-level value is controlled to have a close  
Reference B-level value.  
Reflected recording pulse  
c. Normalization of B-level is used to eliminate the effect of reflectivity fluctuation.  
==> The reflected B-level value is normalized by the disc reflectivity itself.

Recording is done by changing the organic dye layer and the substrate with a laser when a strong is  
applied to a disc, the temperature of the ortanic dye material goes up, the dye is decomposed and the  
substrate changes at the same time. At this time, a durable bit is created as is the case with a CD-ROM.

[Recording]  
When a high-power laser is applied to the recording material, it melts and then becomes amorphous with  
a low reflection coefficient when it quickly cools off. When a mid-power laser is applied to heat gradually  
the recording material and then gradually cools it off, it becomes crystal with a high reflection coefficient.  
[Playback]  
A low-power laser is used for playback. The amount of reflected light depends on the status (amorphous  
or crystalline) of the recording material. This is detected by an optical sensor.

Brief Process  
1. Regional Code for DVD Disc  
– DVD-ROM drive transfers the regional code of the control data to host by the command of host, the DVD  
player of host reads the regional code, and plays title in the case of allowed regional code only.  
2. Management of DVD Disc for the scrambled of data  
(1) DVD-ROM and DVD player of host generate the “KEY 1” respectively, transfer to opposite part, the  
“KEY 2” is received, recognizes the data transfer or not with this value, and generates the bus key  
encoded the data.  
(2) Encoded “Disc Key” and “Title Key” host is transfer with the bus Key.  
(3) DVD player of host reads the key value, and uses the value to restore the scrambled data.

3. About Prevention the DVD-ROM from to be copy  
A data is able to encode and record in the disc, if a copyright holder wants to prevent the disc from copying.  
In case of a disc enhanced movie of 3 titles......  
DISC KEY (2048 Bytes) is used to encode the whole contents in the disc and TITLE  
KEY (5 Bytes) is used to encode the title respectively.  
So, the data is encoded and stored in a disc through the unknown algorithms  
with a disc key and title key. (At this time, the disc key and title key are stored  
in a disc.)  
…As above, the disc is able to copy when the disc key and title key are  
opened.  
Then, ROM-DRIVE encodes the disc key and title key and transfers to MPEG-  
2 board.  
If you want to play the disc prevented from the copy......  
First of all, ROM-DRIVE and MPEG-2 board identify with each other through the procedure as described  
below.  
AGID  
HOST  
ROM-DRIVE  
Challenge key  
MPEG-2  
BOARD  
encoded disc key, title key  
1. Drive and host gives and takes the ID of 2bit. This ID is AGID (Authentication Grant ID).  
The various decoder boards are attached to the host, in these, AGID sets the MPEG-2 board and drive.  
2. After the AGID is set, MPEG-2 board generates the challenge key (10 Byte) and transfers to drive. The  
board and drive generate key 1 (5Byte) with the challenge key respectively. (Of course, the Algorithm  
generating the key 1 is not known.)  
3. Compare with the generated key 1, if it corresponds each other, the first step of authentication is  
completed. This is a course to identify the MPEG-2 board with a drive.  
4. The second step of authentication is a course to identify a drive with the MPEG-2 board.  
The dirve generates a challenge key and transfers it to the MPEG-2 board. The dirve and MPEG-2 board  
generate the key 2 (5Byte) with the challenge key, compare with each other, and if it corresponds and the  
secondary step of authentication is completed.  
5. As above, the identification is completed.  
6. The dirve and MPEG-2 board generate the Bus key with the key 1 and key 2 and own it.  
7. Dirve encodes the disc key and title key with this Bus key and transfers to the MPEG-2 board.  
8. The MPEG-2 board reads the encoded disc key and title key with the Bus key only.  
9. MPEG-2 board lets data read from the drive to decode with the read disc key and title key and makes into  
the video signal by decoding.

1-2. ALPC (Automatic Laser Power Control) Circuit  
ALPC function DVD/CD anlaog front-end IC(IC101 R2S35002) is for constant power control purpose. Based on the  
accurate power sensor(FMON) in P/U, ALPC feedback loop maintains constant power level against laser diode’s  
temperature variation.  
The ALPC loop amplifies(10x) the FMON signal to enhance the accuracy of read power level control. Swithching of  
amplification is made by combination of a logical WGATE signal and a logical RWAPC signal.  
There are two set of APCDAC, which are used at different term to monitor different power level. Generally, the one is used  
at reading and the other one is used at writing. The logical WGATE signal which is switched between reading and writing  
changes the two APCDAC.  
The ALPC loop supplies same currency (IAPC) to Laser Diode Driver(LDD) during reading and writing.  
There is another ALPC which controls Full-Scale-DAC (FsDAC). FsDAC determines scale of WDAC of Laser Diode Driver.  
MPU monitors write-power level of FMON signal and changes FsDAC directly to maintain constant write-power level. There  
are two write power signal. The one is based on S/H signal and the other one is based on B/H(Bottom-Hold) signal. The  
write power levels are monitored as digital levlels which are converted by built-in Anlog-Digital Converter in DSP. The MPU  
monitors each write power level and calculates proper setting of FsDAC, and changes value through serial interface  
between LDD and DSP.

2-2. Focus Servo  
The aim of Focus Servo is to maintain the distance between object lens of P/U and disc surface, so that the  
detected RF signal(A, B, C, D, EF1, EF2, EF3, EF4) can be maximized.  
Focus Error Signal(FE) generates from focus error detection block in RF IC(R2S35002) using Conventional  
Astigmatism Detection method, Differential Astigmatism Detection method.  
Focus Gain and path can be changed at the RF IC(R2S35002) according to the disc, and the resulting output  
FE(R2S35002 2pin) is input to DSP IC(R2S35002 169pin).  
The Focus Search operation is using FE, PE Signal, therefore check FE, PE signals when Focusing is failed.  
The role of DSP IC(R8J32007) is Focus Digital Controller. The operation path is as follows;  
FE Signal is input to DSP IC(R8J32007 169pin), and after A/D Conversion, Digital Equalizer Block and D/A  
Conversion in R8J32006FP, the output signal FOD(R8J32007 180pin) is input to Drive IC(R2S30202FP 40pin).  
The drive output signal FACT+/FACT- generated according FOIN(R2S30202FP 40pin), and drives focus  
actuator in the P/U unit.

3-2-1. Tracking Servo  
The aim of tracking servo is to make laser beam trace the data track on disc.  
Tracking Error(TE) Signal is generated from tracking error detected block in R2S35002 using DPP(Differential  
Push-Pull) Method and DPD (Differential Phase Detection) Method.  
DPP Method uses not only main beam(A, B, C, D) but also side beam(EF1~EF4) for correcting DC offset  
generated in Push-Pull Method.  
The remaining procedure of TE signal processing in R8J32007 is similar to Focus Servo.  
The role of DSP IC(R8J32007) is Tracking Digital Controller.  
TE Signal is input to DSP IC(R8J32007 173pin), and after A/D Conversion, Digital Equalizer Block and D/A  
Conversion in R8J32007, the output signal TRD(R8J32007 181pin) is input to Drive IC(39pin).  
The drive output signal TACT+/TACT- generated according TOIN(R2S30202FP 39pin), and drives tracking  
actuator in the P/U unit.  
3-2-2. Sled Servo  
The working distance of tracking actuator is too short to cover whole disc radius.  
Sled Servo make P/U move by little and little so that the laser beam keep tracing the data track on disc  
continuously when tracking actuator reaches the working limit.  
TE Signal is input to DSP IC(R8J32007 173pin), and after A/D Conversion, Digital Tracking Equalizer Block,  
Digital Sled Compensator Block and D/A Conversion in R8J32007, the output signal SL1, SL2(R8J32007 182,  
183pin) is input to Drive IC (R2S30202FP SL1:3 pin, SL2:2pin) after Low-Pass filtering.

5) DVD 12x CAV : DVD-ROM DL  
6) DVD 16x CAV : DVD-ROM  
7) DVD 16x PCAV : DVD+R  
When drive read PRESS CD, Closed Session CD-R/RW, the spindle motor is controlled using FG CAV Spindle  
Servo. FG signal(R2S30202FP 19pin) input to SFG in DSP IC(R8J32007 213pin).  
The spindle controller in DSP IC uses SFG as spindle rotation frequency feedback, therefore the FG CAV  
Spindle Servo doesn't work well if FG generation is abnormal.  
The spindle controller PWM output signal SPD(R8J32007 211pin) input to SPIN in Drive IC(R2S30202FP 1pin)  
after Low-Pass Filtering.  
The PWM output signal U, V, W signal(R2S30202FP 12, 13, 14pin) drives Spindle Motor without using a  
sensor, and FG pulse output is generated as 18 pulses/rotation.

When drive write DVD-RAM/R/RW/+R/+RW/CD-R/CD-RW, the spindle motor is controlled using Wobble CLV  
Spindle Servo.  
The WOBSIG signal(R2S35002 37pin) input to DSP IC(R8J32007 154pin). The DSP Controller in R8J32007  
uses WOBSIG as linear velocity feed back, therefore the Wobble CLV Spindle Servo doesn’t work well when  
WOBSIG signal is abnormal.  
The spindle controller PWM output signal SPD (R8J32007 211pin) input to SPIN in Drive IC(R2S30202FP 1pin)  
after Low-Pass Filtering.

HW Self- Diagnostic function  
1. Self-Diagnostic Function by LED Blink.  
• Basic operation: At JR6, MPU is included in DSP, MPU accesses each peripheral (inside, exterior) device,  
and discover a defect by the ability of a read/write of data to be performed correctly. Since MPU operates by  
the program with a built-in Flash-ROM, when abnormalities are in MPU, Flash-ROM, and these Data-Bus &  
control signals, this self-diagnostic function cannot be used. In such a case, the case where LED does not  
light up at all at the time of a power supply injection is almost the case.  
• MPU: In DSP Flash-ROM (16Mb) is connected to the exterior Bus of MPU. Even if the MPU-Bus terminal of  
Flash-ROM short-circuits, it becomes impossible for MPU to read the right program data from Flash-ROM,  
and stops for this reason, turning on LED at all. On the other hand, the own poor device of DSP, and the  
open state of IC-pin, when a defect does not influencing Bas of MPU, it can detect correctly and becomes  
blink of LED according to those defects.  
• DSP: DSP has ATAPI-IF, LDD-serial-IF, AFE-serial-IF, and an AFE control signal as Digital-IF. As Analog-  
IF, it has the slice circuit of RF signal from AFE, PLL, the objects ADC and DAC for SERVO, and ADC for  
ADIP detection. Among these, own poor Digital of DSP, and AFE-serial-IF can detect by this self-diagnostic  
function.  
• AFE: Poor detection of AFE is restricted to detection of a limitation-item. Since the greater part of the  
function is analog signal processing, AFE serves as a register in AFE, and a check, which accepts it, serial  
IF in the logical digital examination from MPU. In addition, serial-IF for AFE control is performed via DSP.  
This is writing in the Write command and setting data, and is automatically transmitted to the predetermined  
register of DSP. Conversely, when it leads the register information on AFE, the read command can be  
written in the predetermined register of DSP, and the value of an AFE register can be read by reading the  
read register of DSP after that. Therefore, serial [between the poor register of AFE, and AFE and DSP],  
when there is LED blink with poor AFE — the defect of IF or the defect of the register for AFE of DSP is  
considered.  
• Refer to the contrast table of the number of times of blink of LED, and a poor part.  
• The self-diagnostic function by this LED blink is carried out in the state of a set without a PCB independent  
or loading Disc.

=> It repairs, when abnormalities are discovered.  
(2) Does the power supply circuit operate normally?  
External input 12V, external input 5V, regulator 3.3V, regulator 2.8V, and regulator 1.5V  
=>When the abnormalities are discovered, an external power supply, a power supply cable, and Regulator  
IC are exchanged.  
=> Since a problem is in a load side when not improving, even if it exchanges the above, and attached sheet  
JR6 power-supply system figure is made reference, and poor portions, such as a short circuit of a power  
supply part, are found out and fixed.  
(3) Is the clock of MPU in DSP oscillated correctly?  
Checked the ceramic oscillation element’s X301 both-ends and DSP(106)(107) 33.87MHz oscillating.  
=> When 3.3V power supply is correctly supplied to DSP and the clock is not oscillating correctly, it is the  
defect of MPU, or an oscillation element defect, and part exchange is performed in order of DSP and  
X301.  
(4) The defect of Flash-ROM  
Although the clock of DSP is oscillating correctly and the power supply circuit is also outputting normal  
voltage, when LED does not blink at all at the time of a power supply injection and Eject-SW does not react,  
either, poor Flash-ROM is the most doubtful.  
=> Flash-ROM (IC302) are exchanged.  
Note: Before Flash-ROM exchange, the CS signals of the external device of MPU in DSP connection, an  
Address signal, and a Data signal are observed on a waveform level, and since the but most amount of work  
and the special knowledge which can raise the discovery accuracy of a poor part are necessities,  
recommendation is impossible.  
(5) Even if it performs the above-mentioned repair, when not improving, the disconnection and the short circuit  
which cannot be discovered, can be considered in viewing of PCB. Moreover, partial breakage (although a  
clock is oscillated, somewhere in insides do not operate.) of DSP can be considered.  
=> When not improving above, the possibility that a PCB pattern is faulty is high, and judges repair to be  
difficult.

3. Motor, Abnormalities in Actuator System  
The drive circuit of a motor & actuator consists of the three ICs IC601(R2S30202FP). The work of each IC is  
as follows.  
(1) IC601(R2S30202FP) : 7ch driver  
Spindle motor driver: 180° audio drive Type, an analog input, a PWM drive, a Vm=12V.  
Stepping motor driver X2: analog input, a PWM drive (differential), a Vm=12V  
Loading motor driver: Input/Output PWM drive, Vm=5V.  
Focus actuator driver: analog input / output (differential), a Vm=5V  
Tracking actuator driver: analog input / output (differential), Vm=5V  
Tilt actuator driver : analog input/output (differential), Vm=5V.
