pregap : A mixed-mode CD encoding format designed to hide the computer data at the front of the audio portion of the CD, between index 0 and index 1 of track one. A CD player still thinks itís an audio-format CD, while a computer thinks itís a CD-ROM. Pregap improves upon mixed-mode by not allowing the audio user to access the Enhanced CD track directly, but there are other problems: patent disputes and a bug in Windowsí95 makes the pregap track inaccessible to PC users.
