This is a recording method that enables adding of
data using the Track-At-Once method.
Conventional CDs begin at a CD control area called

Multi Session CD is a CD having multiple sessions,
with each segment from Lead-in to Lead-out
regarded as a single session.

Music discs encoded with
copyright protection
technologies
This product is designed to playback discs that
conform to the Compact Disc (CD) standard.
Recently, various music discs encoded with
copyright protection technologies are marketed
by some record companies. Please be aware that
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 only
the first session will be played back.
• 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.
