Music discs encoded with copyright
protection technologies
This product is designed to play back
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.
Note on DualDiscs
A DualDisc is a two sided disc product
which mates DVD recorded material on one
side with digital audio material on the other
side. However, since the audio material side
does not conform to the Compact Disc (CD)
standard, playback on this product is not
guaranteed.
Difference in File structures 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 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 files
• Maximum number of groups: 256
• Maximum number of files: 999
Playing order of ATRAC CDs and MP3 CDs
For ATRAC CDs, files are played in the order
selected in SonicStage.
For MP3 CDs, the playing order may differ
depending on the method used to record MP3
files on the disc. A “play list” which contains
an MP3 file playing order can also be played.
In the following example, files are played in
order of to .
File
MP3
Group
(Maximum directory levels: 8)
Notes
• If ATRAC files and MP3 files are recorded on the
same CD, this CD player plays the ATRAC files
first.
• 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 ATRAC/MP3 files, do not save
files in other formats and do not make unnecessary
folders.
About ATRAC CDs
• CD-Rs/CD-RWs recorded in the ATRAC format
cannot be played on your computer.
About MP3 CDs
• Be sure to add the file extension “mp3” to the file
name. However, if you add the extension “mp3”
to a file other than an MP3 file, the player will not
be able to recognize the file properly.
• 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 up to the maximum capacity at one time
on media that has nothing recorded on it, set the
writing software to “Disc at Once.”
