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 host PC is interrupted, Buffer Underrun Protection is
activated to keep precious CD-R discs from going to waste. (

● Optimum Write Speed Control
Before writing to a CD-R, the CRW2200 drive checks the disc’s capability and
automatically selects the optimum writing speed for greater reliability.
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.
High-fidelity digital audio
The CRW2200 drive supports extraction of digital audio data at up to 40X speed, as
well as the recording of digital sound with complete fidelity even when writing at
20X speed. Also, the built-in digital audio output is ideal for the pure transmission of
an audio signal when connected to the SPDIF (digital audio) input of the computer's
sound card.
CD TEXT support
Information such as the song name or artist name can be recorded on Audio CDs
using CD creation software. The text data on the created disc can be displayed on a
CD player that is compatible with the CD TEXT format.
