Yamaha announces CRW2100 (16/10/40)


You read the news here first, it's time for the official press release:

"...Yamaha announces the introduction of the industry's fastest internal and external rewritable CD recorders. The all-new, multi-platform LightSpeed CRW2100 Series models are capable of recording on CD-R discs at an industry-first top speed of 16X, writing a 74-minute CD in under five minutes; rewriting CD-RW discs at a top speed of 10X; and reading CDs at a sustained maximum rate of 40X. In addition, the CRW2100 Series allows users to rip audio CDs at a maximum speed of 40X.

To achieve the industry's fastest CD-R write speed, Yamaha developed the CRW2100 Series to take advantage of the partial Constant Angular Velocity (CAV) technology, a combination of CAV and standard Constant Linear Velocity (CLV), for optimum performance. To rewrite a CD-RW disc at up to 10x speed, the Lightspeed recorders use the full CAV recording method.

The CAV recording method keeps the disc rotation speed constant while adjusting the data transfer rate, depending upon which portion of the disc is being recorded. For writing CD-R discs, the CRW2100 Series uses CAV in the inner portion of the disc while using CLV in the outer portions in order to deliver a top writing speed of 16X. Also known as partial CAV, this method enables a significant increase in the data transfer rates while minimizing the load increase to the drive's mechanism.

In pursuit of perfecting reliability, Yamaha has also equipped the CRW2100 Series with Optimum Write Speed Control. By checking a disc's capability and the recording conditions, this new technology allows the LightSpeed recorders to select the optimum writing speed to further improve reliability. The CRW2100 Series recorders also incorporate Yamaha's Waste-Proof Write Strategy. Unlike other write strategies which rely heavily on data-links and error corrections, Yamaha's write strategy focuses on providing a robust, stable recording environment by combining a large buffer memory, CAV writing support for on-the-fly data backup, and specific fine-tunings to the recording software. This strategy maximizes harmony between the recorder and the PC, virtually eliminating buffer underruns and preventing waste of media.

The CRW2100 series recorders offer an extra large 8 MB buffer memory-up to 4X larger than that of competitive recorders-virtually eliminating common buffer underruns. The new LightSpeed recorders are designed to take full advantage of the new, high performance 16X CD-R media to optimize record speed and reliability. Yamaha and other media makers will introduce 74-minute and 80-minute 16x CD-R media in October 2000.

The CRW2100 Series will feature four models: the internal CRW2100EZ using E-IDE (ATAPI) interface will ship in mid-October 2000, and the internal CRW2100SZ using Ultra SCSI (SCSI-3) interface will be available in late October 2000. The external CRW2100SXZ using Ultra SCSI interface will ship in late-November 2000. The external CRW2100FXZ using IEEE 1394 FireWire(TM) technology will be available in early December 2000..."
