The structure of ATRAC CDs
and MP3 CDs
ATRAC CDs and MP3 CDs consist of"files"
and "groups." A "file" is equivalent to a "track"
of an audio CD. A "group" is a bundle ot files
and is equivalent to an "album." For MP3 CDs,
this system recognizes an MP3 folder as a
"group" so that ATRAC CDs and MP3 CDs can
be operated in the same way.

selected in SonicStage. For MP3 CDs, the
playing order may differ depending on the
