The need for such a drive will increase as more CD-ROM XA
software becomes available.
If possible, the drive should support the CD-ROM XA
and Multisession Photo CD specifications.
The proposed development of CD-ROM XA
defines an encoding scheme and format for audio information.
This combines Chinon's 535 Series CD-ROM drives--which boast double-speed technology, 280ms average access speeds, 256K data buffer, full multisession Photo CD and CD-ROM XA
compatibility, and MPC and QuickTime support--with four educational titles.
Doi then invited manufacturers of all computer architectures to join in on CD-ROM XA
to create a "common space" between IBM PCs, Macintoshes and CD-I systems.
Existing CD-ROM drives must be modified in order to read CD-ROM XA
applications, but future drives built to the new standard's specifications will still read the older CD-ROM format.
At the September 1988 CD-ROM Expo, Philips, AIM, Sony and Microsoft hosted a press conference in which they demonstrated a prototype CD-ROM XA
The CD-ROM formats that have evolved since 1986 from the CD-DA (digital audio) format constitute a maddening alphabet soup, ranging from CD-ROM XA
for extended architecture) to CD-I (for interactive) to CD Extra (also known as Enhanced CD, which accommodates audio and data tracks in a fashion that permits the audio to be played on a plain vanilla CD player).
Notice that I didn't write "CD-ROM recording," because this product can record CD-audio, CD-ROM, CD-ROM XA
, CD-R, CD-RW, Video CD, PhotoCD, CD-Extra, and even bootable CD-ROM (a godsend for backing up your system), and can handle single-session, multisession, and mixed-mode formats as well.
Supported formats include ISO 9660, CD-ROM Mode 1 and 2, Mixed Mode, CD-ROM XA
Mode 2 Form 1 and 2, CD-1, Video CD, Hybrid, ISO HFS and UFS, Single- and Multi-Session, DAO and TAO, CD Audio, CD-G, Cd-Plus, Sony PlayStation, and Sega Saturn.
