CD Interactive
Green Book standard

CD developed for CD-i players.  These CDs contain a TOC which is different from normal CDs and therefore lots of CD/DVD-ROM players have big problems with these CDs.  Especially when the CD-i contains both data and audio.  In that case the data can seldom be retrieved using ordinary CD/DVD-ROM units.

There are also CD-i Video CDs out there but they are not according to the White Book standard.
