Features of the CRW-70 Drive

High speed writing/reading

The CRW-70 drive supports up to 12X-speed writing of CD-R discs*1, and up to 8X-speed writing/rewriting of CD-RW discs. The drive also supports data reading and digital audio data extraction at up to 24X 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 USB 1.1 standard. USB’s hot plug 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.

Buffer Underrun Protection

When data transfer from the computer is interrupted, Buffer Underrun Protection is activated to keep precious CD-R discs from going to waste. (→P. 7)

Optimum Write Speed Control

Before writing to CD-R discs, the CRW-70 drive checks the disc’s capability and automatically selects the optimum writing speed*2 for greater reliability. The speed you set with your CD writing software 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.
