About ATRAC CDs and MP3 CDs 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 of 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.
