File structures of ATRAC CDs and MP3 CDs
ATRAC CDs and MP3 CDs consist of
“les” and “groups.” A “le” is equivalent
to a “track” of an audio CD. A “group”
is a bundle of les and is equivalent to an
“album.”
For MP3 CDs, this CD player recognizes an
MP3 folder as a “group” so that ATRAC CDs
and MP3 CDs can be operated in the same
way.
The usable number of groups and les
– maximum number of groups: 255
– maximum number of les: 999
Playing order of ATRAC CDs and MP3 CDs
For ATRAC CDs, les are played in the order
selected in SonicStage.
For MP3 CDs, the playing order may differ
depending on the method used to record
MP3 les on the disc. A “play list” which
contains an MP3 le playing order can also
be recorded. In the following example, les
are played in order of to .

Notes
• If ATRAC3plus/ATRAC3 les and MP3 les are
recorded on the same CD, this CD player plays the
ATRAC3plus/ATRAC3 les rst.
• The playback capability of this CD player may
vary depending on the quality of the disc and the
condition of the recording device.
• Acceptable characters are A to Z, a to z, 0 to 9,
and _(underscore).
• On a disc that has ATRAC3plus/ATRAC3/MP3
les, do not save les in other formats and do not
make unnecessary folders.
About ATRAC CDs
• CD-Rs/CD-RWs recorded in the ATRAC3plus/
ATRAC3 format cannot be played on your
computer.
About MP3 CDs
• Be sure to add the le extension “mp3” to the le
name. However, if you add the extension “mp3”
to a le other than an MP3 le, the player will not
be able to recognize the le properly.
• This CD player can play bit rates of 16 to 320
kbps and sampling frequencies of 32/44.1/48 kHz.
Variable Bit Rate (VBR) les can also be played.
• To compress a source in an MP3 le, 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 up to the maximum capacity at one time
on media that has nothing recorded on it, set the
writing software to “Disc at Once.”
