The usable number of groups and files
• Maximum number of groups: 255
• Maximum number of files: 999
Settings for compression and writing software
• This CD player is able to play MP3 files with the following specifications: Bit rate:
16 - 320 kbps, and sampling frequencies: 32/44.1/ 48 kHz. Variable Bit Rate (VBR) file can
also be played.
To compress a source for an MP3 file, we recommend setting the compression software to
“44.1 kHz,” “128 kbps,” and “Constant Bit Rate.”
• To record up to the maximum capacity, set to “halting of writing.”
• To record at one time up to the maximum capacity on media that has nothing recorded on it,
set to “Disc at Once.”
Notes on saving files on the media
• Do not save files in other formats (except MP3/ATRAC3plus/ATRAC3 format files) or
unnecessary folders on a disc that has MP3 files.
• When a disc is inserted, the CD player reads all the information of folders and files on that
disc. If there are many folders on the disc, it may take a long time for play to begin or for the
next file to start playback.
The structure of ATRAC3plus/ATRAC3 and MP3
files
Groups and folders
The ATRAC3plus/ATRAC3 format has a very simple structure. It consists 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.” A “group” has no directory-type structure (a new group cannot be
made within an existing group).
When referring to MP3 CDs, “file” is equivalent to a “track” and a “group” is equivalent to an
“album.” This CD player is designed to recognize an MP3 folder as a “group” so that it can play
CD-Rs/RWs in the same manner as it plays ATRAC3plus/ATRAC3 files.
