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
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 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.

Partial Constant Angular Velocity (P-CAV) technologyPartial Constant Angular Velocity (P-CAV) technology

Partial Constant Angular Velocity (P-CAV) technology

Partial Constant Angular Velocity (P-CAV) technologyPartial Constant Angular Velocity (P-CAV) technology

The Partial Constant Angular Velocity (P-CAV) recording method is a
combination of the Constant Angular Velocity (CAV) and Constant Linear
Velocity (CLV) recording technologies. In CAV recording technology, the
drive maintains a consistent rotation speed which will result in a variable
transfer rate, while in CLV recording technology, the data transfer rate is
kept at a fixed level by changing the rotation speed.

P-CAV recording technology switches from CAV to CLV once the maximum
transfer rate is reached. Unlike Zone Constant Linear Velocity (Z-CLV)
recording, no links are produced in the P-CAV recording process, resulting
in a higher average transfer rate.

The following illustration shows the Partial Constant Angular Velocity
(P-CAV) recording technology.
