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: 255

–maximum number of files: 999

Notes

•If ATRAC3plus/ATRAC3 files and MP3 files are recorded on the same CD, this CD player plays the ATRAC3plus/ATRAC3 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 ATRAC3plus/ATRAC3/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 ATRAC3plus/ ATRAC3 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.

•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) files 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 up to the maximum capacity at one time on media that has nothing recorded on it, set the writing software to “Disc at Once.”
