About discs

Disc structure

A DVD disc consists of “titles,” and each title may be divided into some “chapters.”

For example, if a DVD disc contains some movies, each movie may have its own title number, and it may be further divided into chapters.

	Title 1		Title 2
Chapter 1	Chapter 2	Chapter 3	Chapter 1 Chapter 2

A VCD, SVCD, and Audio CD consist of “tracks.”

In general, each track has its own track number. (On some discs, each track may also be divided with Indexes.)

Track 1 Track 2 Track 3 Track 4 Track 5

On an MP3 disc, each song is recorded as a track (file). Tracks are usually grouped into a group (folder). Groups can also include other groups, creating hierarchical group layers. This system can recognize up to 150 tracks per group, and up to 99 groups per disc (up to 14,850 tracks).

•If there is any type of files other than MP3 files in a folder, those files are also counted in the total number of 150.

Group 1			Group 2
Track 1	Track 2	Group 3	Group 4	Group 5

On a JPEG disc, each still picture is recorded as a file. Files are usually grouped into a group (folder). Groups can also include another groups, creating hierarchical folder layers. This system can recognize up to 150 files per group, and up to 99 groups per disc (up to 14,850 files).

•If there is any type of files other than JPEG files in a folder, those files are also counted in the total number of 150.
