Yamaha Unveils High Quality Audio CD-R/RW Drives
-- New CRW3200 series offers 24X write, 10X rewrite, and 40X read speeds with SafeBurnTM and Audio Master Quality Recording mode--

Hamamatsu City, Shizuoka, November 20, 2001 - Yamaha Corporation, an established leader in digital audio, today unveiled the CRW3200 series of high quality audio CD-R/RW drives, that promises greater stability, efficiency and offers Audio Master Quality Recording.
Yamaha is presenting four models in the CRW3200 series and the first, the CRW3200E (internal ATAPI), will become available worldwide from the fourth quarter of 2001. |

| 24X writing, 10X rewriting, 40X reading and audio ripping |
|
To develop the CRW3200 series of drives Yamaha increased the maximum recording speed to 24X while retaining many of the earlier models' excellent features. Among these is the incorporation of Partial CAV (Constant Angular Velocity) recording to ensure high-quality recording even at high speeds.
In addition to employing conventional CLV at 2X, 4X, 8X, and 10X in rewriting mode, the CRW3200 also supports the 4X-10X CAV mode. This permits high-speed random writing/reading of data and realizes floppy disk-like ease of operation using packet writing.
CRW3200 series drives also feature a CD-ROM read speed of up to 40X with CAV, expediting the reading of digital audio discs at up to 40X and the extraction of a 74-minute audio CD in about three minutes. |

| SafeBurnTM features ensure stability and ease of use |
|
CRW3200 series drives are equipped with SafeBurnTM features so that all users - whether professional or novice - can have greater confidence in the final recorded result. SafeBurnTM incorporates Buffer Underrun Protection, generous 8MB buffer memory and Optimum Write Speed Control to make for an easier and more stable and efficient CD-recording experience.
The Buffer Underrun Protection packaged in SafeBurnTM frees users from the inconveniences associated with buffer underrun errors by completely eliminating them. With SafeBurnTM, if data transfer is delayed and memory in the buffer drops to a critical level, recording is suspended until the buffer has regained sufficient memory, after which the recording restarts virtually seamlessly from the point at which it was suspended.
While Buffer Underrun Protection prevents buffer underrun errors, the frequent activation of the system would normally extend the time required for the completion of disc writing. The CRW3200 is equipped with an 8MB buffer memory - two to four times larger than that of its competitors - to ensure stable and efficient recording, and to minimize the incidence of suspension of recording caused by buffer underrun.
The Optimum Write Speed Control function that automatically adjusts writing speed to the optimum level for each kind of disc, removes user concerns about recording speeds and the CD-R disc's compatibility. Simply by setting the writing speed at 24X, the CRW3200 checks the characteristics and conditions of the inserted disc and automatically selects the maximum optimum writing speed for the disc to ensure data reliability when the disc is read back by CD-ROM drives or CD players. Here again, Partial CAV permits greater flexibility in speed selection in the 12X-24X speed range, considerably enhancing recording efficiency.

| Audio Master Quality Recording |
|
CRW3200 series drives have an Audio Master Quality Recording mode for writing audio CDs with less digital noise, or jitter. This unique feature enables recording of music CDs with a quality almost equivalent to the master disk.
CRW3200 series drives also incorporate features that ensure reliable recording onto a wide range of media, such as Running Optimum Power Calibration (ROPC) to ensure that optimum laser output power is adjusted for each disc.
Adding to these unique features, CRW3200 adds support for a new packet writing format called CD-MRW (CD Mount Rainier Rewrite). CD-MRW is the next-generation packet writing format, which features background formatting, defect management by the drive, and eject during formatting.

The CRW3200 series features four models to meet users' needs: CRW3200E (internal ATAPI), CRW3200SX (external SCSI-3), CRW3200IX (external IEEE1394), and CRW3200UX (external USB2.0). The CRW3200E will become available worldwide during the fourth quarter of 2001 and the release of other models will follow.

| Yamaha - a leader in CD recording |
|
Since the late 1980s, Yamaha has been the leader in CD-recorder development, producing high performance recorders that redefined industry standards. The company introduced the first programmable CD-recording system in 1988, which it followed with the development of the first 2X speed CD recording system in 1990, and the first 4X half-height CD-R drive in 1993. Yamaha also introduced the first 4X speed writing CD-rewritable drive in 1997, the first 4X speed rewriting CD-rewritable drive in 1998, and the first 8X speed CD-rewritable recorder in 2000. A forerunner to the new CRW3200 series, the CRW2100 that boasted the industry's then fastest writing speed in a CD-R/RW drive, 16X, was unveiled by Yamaha in October 2000.
