Apple CD 300 Product Description
The new high-performance AppleCD 300 drive is the perfect
tool for accessing the world of CD-ROM and multimedia. Designed for use with
the Apple Macintosh personal computer, the AppleCD 300 spins at twice the
speed of ordinary CD-ROM drives to give you much faster access to the
tremendous amount
of information stored on CD-ROM discs. So itÕs easier than ever to work
efficiently with the wealth of commercially available reference libraries,
software, databases, clip art/graphics collections, educational programs,
and games. In addition, the
faster spin speed of the AppleCD 300 means smoother playback of your
QuickTime movies, video, and animation.
But the AppleCD 300 is not just a faster drive, itÕs also a far more
versatile one. With the support of QuickTime, for instance, it can read the
new multi-session Kodak Photo CD discs. Take your original film, negatives,
or slides to designated Kodak centers for conversion into high-quality
images onto a Kodak Photo CD disc. Then--because the
AppleCD 300 can conveniently access Kodak Photo CD images--you can cut and
paste them into your favorite word-processing, presentation, and graphics
applications.
To give you access to the diverse library of CD-ROM titles, the AppleCD300
is compatible with the industry-standard ISO 9660/High Sierra file formats,
as well as with the Macintosh HFS. It is CD-ROM XA-ready and also supports
other CD-ROM formats, such as CD+G and CD+MIDI. It not only plays standard
audio CDs, but can also transfer CD digital audio data via the SCSI bus to
your Macintosh for further editing.
