About “MP3”
What is the MP3?
MP3 (MPEG 1 Audio Layer-3) is a standard
technology and format for compressing a
sound sequence. The file is compressed to
about 1/10 of its original size. Sounds
outside the range of human hearing are
compressed while the sounds we can hear are
not compressed.

You can only play MP3 files recorded by

USABLE MEDIA

USABLE DISC FORMAT
You can use ISO 9660 Level 1/2 and Joliet

like those of Japanese are displayed as “–.”)
The major specification of the usable disc
format is:
• Maximum directory steps: 8
• Usable characters for a file/folder name:
A - Z, 0 - 9, _ (underscore)
• Maximum number of characters for a file
name: 64 and a 3-character extension code
Notes
• When naming, be sure to add the file extension
“mp3” to the file name.
• If you put the extension “mp3” to a file other than
an MP3 file, the player cannot recognize the file
properly.
• The file name does not correspond to the ID tag.
THE USABLE NUMBER OF FOLDERS/
FILES
• Maximum number of folders: 511
• Maximum number of files: 511
SETTINGS FOR COMPRESSION
SOFTWARE AND WRITING
SOFTWARE
• To compress a source for an MP3 file, we
recommend setting the transfer bit rate of
the compression software to “44.1 kHz”,
“128 kbps”, and “Constant Bit Rate”.
• To record up to the maximum capacity, set
to the “halting of writing”.
• To record at one time up to the maximum
capacity on media that has nothing
recorded it, set to “Disc at Once”.
NOTES FOR SAVING FILES ON THE
MEDIA
When the disc is inserted, the player reads all
the files on that disc. If there are many
folders or non-MP3 files on the disc, it may
take a long time for play to begin or for the
next MP3 file to start play.
Do not save unnecessary folders or files other
than MP3 ones in the disc to be used for
MP3 listening.
We recommend that you do not save other
types files or unnecessary folders on a disc
that has MP3 files.
