About MP3/WMA (CDE-9845/CDE-9843 only)
CAUTION
Except for private use, duplicating audio data (including MP3/
WMA data) or distributing, transferring, or copying it, whether for
free or for a fee, without permission of the copyright holder is
strictly prohibited by the Copyright Act and by international treaty.
What is MP3?
MP3, whose official name is “MPEG-1 Audio Layer 3,” is a
compression standard prescribed by the ISO, the International
Standardization Organization and MPEG which is a joint
activity institution of the IEC.
MP3 files contain compressed audio data. MP3 encoding is
capable of compressing audio data at extremely high ratios,
reducing the size of music files to as much as one-tenth their
original size. This is achieved while still maintaining near CD
quality. The MP3 format realizes such high compression ratios
by eliminating the sounds that are either inaudible to the
human ear or masked by other sounds.
What is WMA?
WMA, or “Windows Media™ Audio,” is compressed audio
data.
WMA allows you to create music files and store them at higher
ratios of compression than MP3 audio data (approx. half
original size). This is achieved while still maintaining CD
quality sound.
Method for creating MP3/WMA files
Audio data is compressed by using MP3/WMA specified
software. For details on creating MP3/WMA files, refer to the
user's manual for that software.
MP3/WMA files that can be played back by this device have
the file extension “mp3” / “wma”. Files with no extension
cannot be played back. (WMA ver. 7.1, 8 and 9 are
supported)

9841 only) is displayed.
The tag information may not be correctly displayed,
depending on the contents.
Producing MP3/WMA discs
MP3/WMA files are prepared, then written to a CD-R or CD-
RW using CD-R writing software. A disc can hold up to 510
files/folders (including Root Folders). However, the maximum
number of folders is 255.
Media supported
The media that this device can play back are CD-ROMs, CD-
Rs, and CD-RWs.
