Features  
The ASUS CRW-5224A-U is an External CD-RW drive with 52x Write, 24x  
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.  
FlextraSpeedTechnology  
The ASUS FlextraSpeedtechnology provides the optimum solution to  
ensure quality recording when using discs that require flexible speeds. The  
CRW-5224A-U 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 FlextraSpeedtechnology 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 motors life and ensuring  
high-quality recording.

FlextraLinkTechnology  
The ASUS FlextraLinktechnology provides a seamless combination of  
flexibility and ultra-reliable recording quality.  
FlextraLinkincorporates 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. FlextraLinkuses 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 FlextraLinkrecording  
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 massthat 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 Technology  
The CRW-5224A-U 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. This is primarily  
advantageous for computer applications.
