DISCRIBE CD Mastering Software

Disc or Optical Disc Throughout this glossary, disc

with a “c” is used for optical media, since that is the

spelling used in the standards deﬁning compact discs.

Contrast with “disk”.

Disc-At-Once A method of recording a CD-R disc that

is best suited for mastering a Compact Disc for repli-

cation. With Disc-At-Once recording, the Lead-In is

written ﬁrst, followed by the data or audio tracks, and

then the Lead-Out is recorded. In this way, the record-

ing laser is never turned off and no “link” blocks are

written to link the tracks, Lead-In, and Lead-Out areas,

as occurs when a disc is recorded in Track-At-Once.

Disc Image See ISO Image.

Disk Hard disk or ﬂoppy disk or diskette. Refers to

magnetic storage media, as opposed to disc, which re-

fers to an optical storage medium.

DVD Stands for Digital Versatile Disc, a high capacity

disc that looks like a CD, but is capable of storing up

to 4.7GB worth of data (or up to 130 minutes of

MPEG-2 video with up to 8 channels of audio and 32

tracks of subtitles/menus). Higher capacity DVD discs

are possible with double sided discs, and even discs

with two information layers per side. DVD discs can

only be read by players displaying a “DVD” logo (ex-

ample: DVD-ROM drives & DVD-Video players).

DVD will be available in several “formats”, including

DVD-Video for distribution of consumer movies,

DVD-ROM for computer data applications (including

games & other multimedia content), and DVD-Audio

for the ultimate music playback (speciﬁcation not yet

deﬁned). DVD-RAM ReWritable DVD disc with a ca-

pacity of 2.6GB or 4.7G, and using the Micro UDF

logical ﬁle system. Similar to DVD+RW, this re-re-

cordable DVD format is backed by the DVD consor-

tium. Drives should also be capable of reading/playing
