among those discs, there are some that do not
conform to the CD standard and may not be
playable by this product.
Cautions when playing a disc
that is recorded in Multi
Session
· If the disc begins with a CD-DA session, it is
recognized as a CD-DA (audio) disc, and
playback continues until an MP3 session is
encountered.
· If the disc begins with an MP3 session, it is
recognized as an MP3 disc, and playback
continues until a CD-DA (audio) session is
encountered.
· The playback range of an MP3 disc is
determined by the tree structure of files
produced by analyzing of the disc.
· A disc with a mixed CD format will be
recognized as a CD-DA (audio) disc.
