Speed and Stability in New CD-R/RW drives
New CRW2200 series
offers world's first 20X write, 10X rewrite, and 40X read speeds - CRW2200 with
SafeBurn to be demonstrated at CeBit 2001--
March 19, 2001 - Yamaha Corporation, an established leader in digital audio,
today unveiled the world's fastest series of CD-R/RW drives, the CRW2200, that
promises greater recording stability, efficiency and ease of use.
The CRW2200, equipped with SafeBurn for enhanced buffer
underrun protection, will make its debut at the opening of the high-technology
tradeshow CeBIT 2001, being held in Hannover, Germany, from March 22 to March
Yamaha is presenting five models in the CRW2200 series and the
first, the CRW2200E (internal ATAPI), will become available worldwide from the
second quarter of 2001.
20X writing, 10X rewriting, 40X reading and audio ripping
develop the CRW2200 series of drives Yamaha built upon the success of the CRW2100
series launched last October, and significantly increased maximum recording
speed to 20X while retaining many of the forerunner's excellent features. Among
these is the incorporation of Partial CAV (Constant Angular Velocity) recording
to ensure high-quality recording even at high speeds.
The result is a series of superbly engineered drives that can
shorten the writing time by up to 14% compared with CRW2100 series.
"With our CRW2200 series we have not compromised quality
for speed," says Masami Takeuchi, General Manager of Yamaha's IT Sales
& Marketing Division. "By adopting Partial CAV we can promise a constant
and controlled rotation speed during data writes to the inner tracks on the
disc. This reduces vibration that corrupts quality," he explains.
addition to employing conventional CLV at 2X, 4X, 8X, and 10X in rewriting mode,
the CRW2200 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
CRW2200 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.
SafeBurn features ensure stability and ease of use
CRW2200 series drives are equipped with SafeBurn features
so that all users - whether professional or novice - can have greater confidence
in the final recorded result. SafeBurn 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.
Buffer Underrun Protection packaged in SafeBurn frees users from the inconveniences
associated with buffer underrun errors by completely eliminating them. With
SafeBurn, 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. Buffer Underrun Protection in the new CRW2200 series
drives employs Oak Technology's buffer underrun protection method in the DSP
and is integrated with Yamaha's own chips to achieve the highest accuracy of
highest level of data continuity possible .
Although 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 CRW2200 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
by buffer underrun.
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 20X, the CRW2200 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-20X speed range, considerably enhancing recording efficiency.
High quality writing
High quality as well as high speed writing is ensured with the
CRW2200 by the incorporation of Yamaha's proprietary Pure Phase Laser System
that stabilizes laser power and eliminates unwanted reflections and glare produced
when recording a CD, resulting in more accurate recording.
CRW2200 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.
Wide variety of models
The CRW2200 series features five models to meet users' needs:
CRW2200E (internal ATAPI), CRW2200S (internal SCSI-3), CRW2200SX (external SCSI-3),
CRW2100IX (external IEEE1394), and CRW2200UX (external USB2.0). The CRW2200E
will become available worldwide during the second quarter of 2001 and the release
of other models will follow.
