Yamaha Corporation of America announces the introduction of the industry's
fastest internal and external ReWritable CD recorders. The all-new,
multi-platform LightSpeed(2)(TM) CRW2200 Series models are capable of
recording on CD-R discs at an industry-first top speed of 20X, writing a
full CD in under four minutes; rewriting CD-RW discs at a top speed of 10X;
and reading CDs at a sustained maximum rate of 40X. In addition, the CRW2200
Series allows users to rip audio CDs at a maximum speed of 40X-up to 66
percent faster than conventional CD-RW recorders currently in the
marketplace-allowing digital audio extraction of a 74-minute audio disc in
less than three minutes.
To achieve the industry's fastest CD-R write speed, Yamaha developed the
CRW2200 Series to take advantage of Partial Constant Angular Velocity
(P-CAV) technology, a combination of CAV and standard Constant Linear
Velocity (CLV) technology, for optimum performance. 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.
In addition to utilizing conventional CLV recording 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 packet writing. Yamaha CRW2200 CD-RW
recorders will also be the first CD recorders to use the Yamaha SafeBurn(TM)
System with its exclusive Triple Protection Architecture(TM). The SafeBurn
System provides the new recorders with an advanced buffer underrun control
system, an 8MB buffer and Yamaha's Optimum Write Speed Control(TM) which, by
checking a disc's capability and the recording conditions, allows
LightSpeed(2) recorders to select the optimum writing speed to further
improve reliability.
With SafeBurn(TM) advanced buffer underrun control technology, if data
transfer is delayed and memory in the buffer drops below 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. This new buffer underrun protection uses a
combination of Oak Technology digital signal processor (DSP) and Yamaha's
own digital signal and analog front-end processing chips, integrating the
two cutting-edge technologies to achieve the highest level of data
continuity possible.
While most buffer underrun protection systems prevent buffer underrun
errors, the frequent activation of such systems would normally extend the
time required for the completion of disc writing and could affect the disc's
reliability. The Lightspeed(2) recorders are equipped with an 8MB buffer
memory-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.
Another component of the SafeBurn system is the Optimum Write Speed Control
function that automatically adjusts writing speed to the optimum level for
each unique blank disc used, addressing issues regarding recording CD-R
disc's compatibilities for high speed recording. CRW2200 recorders check the
characteristics and conditions of the inserted disc and automatically select
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 ranges, considerably enhancing recording efficiency. CRW2200 Series
recorders 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.
Yamaha has also equipped the CRW2200 Series with an award winning new
software suite for both IBM and Macintosh compatibles, designed to enhance
CRW2200's superfast write/rewrite and audio ripping abilities. The new CD
Mastering software included in CRW2200 Series includes Ahead Software's
award-winning Nero, along with the new InCD for packet writing, NeroMIX for
audio ripping, Nero Wave Editor for audio file editing, and Nero Toolkit to
troubleshoot other components of the system including CD-ROM or DVD-ROM
drives used for digital audio extraction. Also included in CRW2200 External
format models are Ahead Software's NeroMAX for CD Mastering using Macintosh
computers. All U.S. retail pack LightSpeed(2) recorders also feature Adobe's
PhotoDeluxe (for IBM) and PhotoShop LE (for Mac) digital imaging products.
Yamaha's new LightSpeed(2) family will feature five models: the internal
CRW2200EZ using E-IDE (ATAPI) interface, shipping in May 2001; the internal
CRW2200SZ using Ultra SCSI (SCSI-3) interface; the external CRW2200SXZ using
Ultra SCSI interface and the external CRW2200FXZ using IEEE 1394
FireWire(TM) technology, available in June 2001. The FireWire connection
provides simple installation, reliable performance and fast recording
speeds. All models are compatible with IBM PC compatibles and Macintosh
computers. The external CRW2200 USB 2.0 model will be available in late July
2001. |
