Features
The ASUS CRW-5232AS-U is an external CD-RW drive with 52x Write,
32x ReWrite, and 52x Read capabilities. The drive complies with the
Universal Serial Bus 2.0 (USB 2.0) specifications and comes equipped
with the latest innovative technologies in CD recording.
ASUS External CD-RW drives are accentuated by the latest innovations in
CD-recording technology, namely: FlextraSpeedTM, FlextraLinkTM, DDSS II
(Double Dynamic Suspension System II) and the Constant Angular
Velocity (CAV) recording method.
The following sub-sections describe these technologies in detail.
FlextraSpeed™ technology
The ASUS FlextraSpeed™ technology provides the optimum solution to
ensure quality recording when using discs that require flexible speeds. The
drive employs this technology that allows automatic recording speed
adjustment based on the recording media.
In addition to the fact that there are low and high quality recording media,
various other factors such as dye layer, temperature, humidity, dust,
fingerprints, etc., affect the recording characteristics of CD-R and CD-RW
discs. Due to these factors, some discs may not be able to stand the high-
speed capabilities of the latest CD-RW drives. The FlextraSpeed™
technology solves this problem by automatic assessment of the disc
quality and recording capability. The recording speed is based on these
factors. If you use a high quality recording disc, you can maximize the
recording capability of the drive and get the best quality output. If you use
a low quality disc, the drive speed adjusts to the level that is most
appropriate for the disc, still optimizing the disc recording capability.
The FlextraSpeed™ technology also helps maintain the CD-RW drive
because of the controlled motor rotation speeds and reduced noise
caused by spindle air, thus prolonging the drive motor’s life and ensuring
high-quality recording.

FlextraLink™ technology
The ASUS FlextraLink™ technology provides a seamless combination of
flexibility and ultra-reliable recording quality.
FlextraLink™ incorporates a flexible strategy that prevents buffer underrun
problems caused by an empty data buffer. This CD-RW drive technology
allows continuous monitoring of the data buffer status during the write
process. Once the available data drops to approximately 1% of the total
buffer capacity, the drive stops recording and marks the last write position.
When new data is received from the host, it is loaded to the data buffer,
and the laser is repositioned to link the new data with the data already
written. FlextraLink™ uses minimal system resources so that your PC
remains fully operational throughout the writing process, and available for
other applications.
The diagram below shows the advantage of the FlextraLink™ recording
technology.

Double Dynamic Suspension System (DDSS II)
The DDSS II is an enhanced follow-up to the DDSS anti-vibration system
developed by ASUS. The DDSS CD-ROM technology is designed to
reduce the vibration generated from spindle rotation of over 8900 rpm of
40X CD-ROM drives. The DDSS II improves this feature by handling up to
over 10,000 rpm of the new 50X drives. In addition, the DDSS II stabilizes
the pick-up head of the drive in both horizontal and vertical directions,
making tracking and focusing even more precise.
Like the DDSS, the DDSS II vibration absoption structure contains a
“dynamic mass” that can absorb the vibration caused by high revolution of
spindle motor. However, the DDSS II moves the dynamic mass to be
suspended to the chassis, thus providing more stability and accuracy
when accessing data from the disc.
The following diagram illustrates the DDSS/DDSS II design structure.

Constant Angular Velocity (CAV) recording
The drive employs the Constant Angular Velocity (CAV) recording method.
With CAV recording, the drive spindle motor rotates the disc at the same
speed regardless of the radial position of the pickup head. This means that
there is a higher transfer rate when writing data to the outer tracks of the
disc than to the inner tracks, as the head traverses a longer linear path on
the outer than the inner part of the disc.
Although the transfer rates vary, and may not be at maximum, depending
on the part of the disc being written to, the CAV method allows faster
recording speed because the rotation speed does not have to change
when the head writes data to different areas of the disc.
