*1
and up
to 10X-speed writing/rewriting of CD-RW discs.
*2
Furthermore, the drive supports
data reading and digital audio data extraction at up to 40X speed.
USB 2.0 compatible
USB 2.0 provides high-speed data transfer capability (max. speed 480 Mbits/sec.).
The transfer speed is about 40 times faster than the conventional USB standard
(USB 1.1).
USB’s hot swapping capability allows the drive to be plugged in and unplugged even
with the computer turned on.
SafeBurn™ (Enhanced write stability technology)
Generous 8MB of buffer memory
Because of the large data storage area, stable disc writing is possible even at fast
speeds.

for greater reliability. The speed
you set is the maximum writing speed.
Reliable writing
Yamaha’s proprietary Pure-Phase Laser System (patent applied for)
This technology reduces phase interference of the laser beam, so that it projects
accurately onto the disc. Jitter value, an important measure of recording quality, has
been improved 25% compared with Yamaha models not using this technology.
Running OPC (Optimum Power Control)
Running OPC automatically adjusts the output of the laser according to the
characteristics of the disc being used. Running OPC provides greatly enhanced
recording reliability for various manufacturer’s discs.
