How are MP3 files recorded and played back?

MP3 “tracks (files)” can be recorded in “group”—folders in PC terminology.

During recording, the tracks and groups can be arranged similarly to the tracks and folders of computer data. “Root” is similar to the root of a tree. Every track and group can be linked to the root.

In compliance with ISO 9660, the maximum allowable depth of nested directories—so called “hierarchy”—is eight (inclusive of the root).

Playback order, track search order, and group search order of the MP3 tracks recorded on a disc are determined by the writing (or encoding) application; therefore, playback order may be different from the one you have intended while recording the groups and the tracks.

The illustration shows an example of how MP3 tracks are recorded on a CD-R or CD-RW, how they are played back and how they are searched for on this unit.

•The numbers in circles next to the MP3 tracks ( ) indicate the playback order and search order of the MP3 tracks. Normally this unit plays back MP3 tracks in the recorded order.

•The numbers inside the groups indicate the playback order and search order of the groups on an MP3 disc. Normally this unit plays back MP3 tracks in the groups in the recorded order.

The groups marked with asterisk (*) will be skipped since they do not include any MP3 tracks.
