NOTES ON MP3 DISCS
An MP3 file stores audio data compressed using
scheme. In this manual, we refer to what, in PC terminology, are called "folders" and "Files"
as "albums" and "tracks" respectively.
Notes on playing MP3 discs
• An MP3 track must be recorded on a disc
however, that system may not play tracks in the order they were recorded.
• The maximum allowable number of tracks and/or albums in a disc is 255,
albums (directory).
• The maximum allowable depth of a nested folder is 8, including tracks. Note that since the
maximum path length is 128 characters long, the total number of characters including
slashes, hyphens and underscores from the root album name to the track name must be
less than 128.
• If a disc contains audio tracks and MP3 tracks, the system can only play audio tracks.
• The system can play multi-session discs correctly.

44,1 kHz and a fixed or variable bit rate.
