2-3] How do I know what format a disc is in?

(2001/07/09)

You can usually tell by looking at the packaging and/or the disc itself:

- CD-DA discs will have a "Compact Disc Digital Audio" logo.
- CD+G discs will have the words "CD Graphics" (and perhaps even
CD-EG "Extended Graphics").
- CD-i discs will have a "Compact Disc Interactive" logo.
- VideoCD discs will have a "Compact Disc Digital Video" logo
and/or the words "VideoCD".
- PhotoCD discs will most likely say "Kodak PhotoCD" on them.
- SVCD discs have a "Super Video CD" logo (the words "Super Video"
under the standard CD logo). The discs use one of the standard
CD-ROM formats.
- DVCD discs say "DVCD"?? [ can't find much info about DVCD ]
- HDCD (High Definition Compatible Digital) have an "HDCD" logo. See
http://www.hdcd.com/. The discs appear to use the standard Red Book
format.
- SACD (Super Audio Compact Disc) is relatively new. The discs can
have two layers, one of which is in Red Book audio format, the other
in a DVD-like format offering higher fidelity.
- DTS (Digital Theater Surround) CDs are just like normal CDs, but
use DTS encoding instead of PCM. See (2-34).

VideoCD is different from CD-Video (a/k/a "Compact Disc Video", or CD-V).
CD-V is an analog format, like LaserDisc, and the video can't be viewed
with a CD-ROM drive.

There are a few references to Compact Disc MIDI, or CD-MIDI.

See (4-46) for some comments on High Speed CD-RW.
