CD-Recordable
CD-Recordable technology allows production of CD-ROMs on the desktop (one-
offs). It requires a CD-R recorder, appropriate software, a PC, and appropriate
media. CD-Recordable involves a special CD, the one-off blank, very different
from the mass reproduced or “hot-pressed” CDs. It is sold pre-grooved, in 63
or 74 minute capacities, and it involves a layered stru c t u re-with a sensitive
c h e m i c a l recording layer, almost always with a gold reflective layer, and ready for
a CD-Recordable drive. Once re c o rd e d , the CD-Recordable discs (one-offs) perf o rm
in the same way as the mass-re p roduced CDs.
CD-ROM
The Compact Disc-Read Only Memory is the standard 12cm CD formatted
according to the ISO 9660. Although the physical characteristics and track
s t ru c t u re of a CD-ROM are the some as that of CD-Audio, a CD-ROM is used to
store computer data (text, graphics). It also involves additional error detection
and correction.
CD-ROM Drives
The original drives had a transfer rate of 150 KB/second, but recent drives off e r
d o u b l e, quadruple and even higher transfer rates-and are known as 2X, 6X, and
so on. Current drives can handle audio tracks and, for multimedia, have
connections for the sound card. Some recent drives are also XA-ready, and/or
Photo CD ready, with or without multiple session capability.
CD-ROM XA
CD-ROM Extended Arc h i t e c t u re, is used for data, graphics, video, and compre s s e d
audio, in an interleaved scheme (CD-I stru c t u re) making it possible to read and
d i s p l a y jointly text, graphics and audio files of various sample sizes, up to 20
hours of 4-bit mono aural sound. Kodak’s Photo CD for example, uses XA
tracks, and it can therefore be read by an XA drive.
Driver
In computers, driver refers to a device driver, which is software that, under CPU
control, implements device 1/0 functions or other functionality (video, sharing,
graphics, printer, mouse, etc.).
