Glossary
Glossary-3
sion of the Yellow Book
standard, generally consistent
with the ISO 9660 logical format
but designed to add better audio
and video capabilities (taken
from the CD-I standard) so that
CD-ROM can more easily be
used for multimedia applica-
tions. CD-ROM XA is the physi-
cal format for photo CDs and can
also be used for simple data
storage.
CD-RW
Compact Disc-ReWritable. Us-
ing special erasable media in a
CD-RW drive, you can erase the
contents of a CD-RW disc and
write new information to it.
CIRC
Cross-Interleaved Reed-
Solomon Code. The first level of
error correction used in every
CD, and the only one used for
audio CDs. It consists of two
Reed-Solomon codes interleaved
crosswise.
Close Disc
To close (or finalize) a recordable
CD so that no further data can be
written to it. This is done when
the last session’s lead-in is writ-
ten, so a session must be closed
to close the CD.
It is not necessary to close a CD to
read it in a standard CD-ROM
drive; however, you must close
an audio CD to play it in a car or
home CD player.
Close Session
When a session is closed, infor-
mation about its contents is writ-
ten into the CD’s Table of
Contents, and a lead-in and lead-
out are written to prepare the CD
for a subsequent session. It is
necessary to close a session in or-
der to read its contents on an
standard CD-ROM drive, or to
play back an audio CD.
D
d-characters
Capital A to Z, digits 0 to 9, and
the underscore symbol (_).
Data Area
In ISO 9660, the space on a
CD-ROM where the user data is
written. It begins at the address
00:02:16.
Digital Audio Extraction
The process of copying CD-DA
audio tracks digitally, from your
CD-R or another CD-ROM drive
to your hard drive or to a record-
able CD.
Disc-at-Once
A method of writing more than
one track on a CD without turn-
ing off the recording laser be-
tween tracks, so that no run-in
-
run-out blocks are written. It is
preferable to record in Disc-at-
Once mode if you are making an
audio CD to be replicated at a
disc factory.
E
ECC
Error Correction Code. A system
of scrambling data and record-
ing redundant data onto CD as it
is premastered
. When the CD is
read back, this redundant infor-
mation helps to detect and
correct errors that arise during
data transmission.
