CD-ROM - Mode 1 and Mode 2
A supplement to the CD-ROM format which provides an additional error recognition and
correction function. Mode 1 is especially used for computer data and employs a code for error
correction. Mode 2 is used with CD-ROM/ XA and CD-I with audio data and contains an error
recognition code only.

CD-ROM/ XA
CD-ROM/ Extended Architecture. This CD format makes it possible to store computer data and
audio or video data on one track. The different types of data are linked to each other (Interleaving)
so that synchronization problems can be reduced.

Disc At Once
Disc At Once is a method for recording of data onto a CD. With this method, the entire CD is
written in a single process. The CD-recorder first writes a Lead-In, then the data block, and finally
a Lead-Out. In contrast to Track At Once, linking blocks are not used between the individual
tracks with Disc At Once.
