About MP3 Disc
This unit can playback CD discs recorded by the MP3 format (we refer to those discs as MP3 discs in this manual).
Operations for MP3 discs are similar to those for Audio CD discs, though there are some restrictions and differences.
What is MP3?MP3 is the abbreviation of “MPEG1 Audio Layer 3.” MPEG Audio is a compression specification that compresses the audio portion only. This image compression method is used in DVD or Video CD, etc. The audio data has been compressed into about 1/10.
On an MP3 disc, each material (song) is recorded on each Track (file), which usually belongs to a Group (folder).

Group 3
This unit can recognize up to 99 Groups and up to 254 Tracks per Group, however, the number of Tracks to be played back on a disc is limited to 1023.
If a disc includes more than 1023 Tracks, the unit stops detecting Tracks when the number of detected Tracks reaches 1023 and ignores the subsequent Tracks. The unit also ignores any non- MP3 file in the disc.
NOTES for making a private MP3 disc using a●Select “ISO9660” as the disc format.
●Do not select the
●Finalize the disc.
NOTES:
●Because of the disc characteristics or recording condition, some discs may not be played back or it takes time to start playback.
●The unit does not support “packet writing” discs.
●If there are any Tracks (files) which are stored on a disc directly and do not belong to any Group (directory), the unit recognized them as belonging to an independent Group.
●The unit does not output a digital audio signal from DIGITAL AUDIO OUT connector when playing back an MP3 disc.
●The unit plays back Groups/Tracks on an MP3 disc in the alphabetical order.
●For example, if there are three title Groups [one], [two] and [three] on a disc, the playback order is [one], [three] then [two]. Tracks in a Group are played back in the same way.
●Therefore, an MP3 disc on the market may be played back in the different order from the order printed on its sleeve.
