On an optical disc, a track (CD) or title (DVD) is a subdivision of its content. Specifically, it is a consecutive set of sectors (called "timecode frames" on audio tracks) on the disc containing a block of data. One session may contain one or more tracks of the same or different types. There are several kinds of tracks, and there is also a sub-track index for finding points within a track.^{[citation needed]}

Blu-ray discs can also be written in a sequential, session based mode modelled on CD and DVD. A Blu-ray "track" refer to the entire physical storage of a Blu-ray layer; the equivalent to tracks in CD sessions is called a "logical track".^[1]: 36
