Notes on ATRAC CDs
• Maximum number of groups: 255
Maximum number of files: 999
• CD-Rs/CD-RWs recorded in the ATRAC3plus/ATRAC3 format
cannot be played on your computer.
Notes on MP3 CDs
• Maximum number of groups: 100
Maximum number of files: 400
Maximum directory level: 8
• A group that does not include an MP3 file is skipped.
• Be sure to add the file extension "mp3" to the file name.
However, if you add the file extension "mp3" to a file other than
an MP3 file, the player will not be able to recognize the file
properly.
• This player can play bit rates of 16 to 320 kbps, and sampling
frequencies of 32/44.1/ 48 kHz. Variable Bit Rate (VBR) file
can also be played.
• 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."
