The usable number of groups and
files

ATRAC CDs:

• Maximum number of groups: 255

• Maximum number of files: 999

MP3 CDs:

• Maximum number of groups: 256

• Maximum number of files: 511

(The maximum number of MP3 files and groups that
can be contained on a single disc is 512.)

Notes

• The system may be unable to play MP3 files that do

not have the “.MP3” extension.

• Attempting to play non-MP3 files that have the

“.MP3” extension may result in noise or malfunction.

• If ATRAC3plus files and MP3 files are recorded on

the same disc, this system plays the ATRAC3plus
files first.

• On a disc that has ATRAC3plus and MP3 files, do

not save files in other formats and do not make
unnecessary folders.

• To compress a source in an MP3 file, we recommend

setting the compression parameters to “44.1 kHz,”
“128 kbps,” and “Constant Bit Rate.”

• To record up to the maximum capacity, set the

writing software to “halting of writing.”

• To record to the maximum capacity at one time up on

media that has nothing recorded on it, set the writing
software to “Disc at Once.”

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
ATRAC3plus/MP3 sessions are not played
back.

• If the disc begins with an ATRAC3plus/MP3

session, it is recognized as an ATRAC CD/
MP3 CD, and CD-DA (audio) sessions are not
played back.

• The playback range of an MP3 CD 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.
