Features

The ASUS SCB-2408-D is an External Slim CD-RW/DVD-ROM drive with
24x CD-Write, 12x CD-ReWrite, 24x CD-Read and 8x DVD-Read
capabilities. The drive complies with the Universal Serial Bus 2.0
(USB 2.0) and IEEE 1394 specifications and comes equipped with the
latest innovative technologies in CD recording.

ASUS External Slim CD-RW/DVD-ROM drives are accentuated by the
latest innovations in CD-recording technology, namely:

quality recording when using discs that require flexible speeds. The SCB-2408-D
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
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.

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.

Partial Constant Angular Velocity (P-CAV) Recording 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 (Z­CLV) 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.
