Disc construction

In general, a disc comprises of “units” which separate recorded audio and/or video materials.

In the case of a DVD disc, “titles” and “chapters” are the “units.” a disc comprises “titles,” and each title may be divided into some “chapters.” Each title has an independent content, while each chapter in the same title has continuity. For example, if a disc contains some movies, each movie may have its own title number, and each movie may be divided into some chapters. In a karaoke disc, each song usually has its own title number and does not have chapters.

In the case of an audio or video CD, “tracks” are the “units”. Each song usually has a track number. Also, some track may be divided into “indexes”.

Each “unit” described above has a continuous number, which helps you to find the desired position in a disc.
