■MP3 and WMA files
MP3 (MPEG Audio LAYER 3) is a standard audio compression format.
Files can be compressed to approximately 1 /10 of their original size by using MP3
compression.
WMA (Windows Media
TMAudio) is a Microsoft audio compression format.
This format compresses audio data to a size smaller than that of the MP3 format.
There is a limit to the MP3 and WMA file standards and to the media/formats
recorded by them that can be used.

• Disc formats: CD-ROM Mode 1 and Mode 2
CD-ROM XA Mode 2, Form 1 and Form 2
• File formats: ISO9660 level 1, level 2, (Romeo, Joliet) 
MP3 and WMA files written in any format other than those listed above may

played correctly.
Items related to standards and limitations are as follows:
• Maximum directory hierarchy: 8 levels
• Maximum length of folder names/file names: 32 characters
• Maximum number of folders: 192 (including the root)
• Maximum number of files per disc: 255
●File names
The only files that can be recognized as MP3/WMA and played are those with
the extension .mp3 or .wma.
●Multi-sessions
As the audio system is compatible with multi-sessions, it is possible to play discs
that contain MP3 and WMA files. However, only the first session can be played.
●ID3 and WMA tags
ID3 tags can be added to MP3 files, making it possible to record the track title
and artist name, etc.
The system is compatible with ID3 Ver. 1.0, 1.1, and Ver. 2.2, 2.3 ID3 tags. (The
number of characters is based on ID3 Ver. 1.0 and 1.1.)
WMA tags can be added to WMA files, making it possible to record the track
title and artist name in the same way as with ID3 tags.

●MP3 and WMA playback
When a disc containing MP3 or WMA files is inserted, all files on the disc are first
checked. Once the file check is finished, the first MP3 or WMA file is played. To
make the file check finish more quickly, we recommend you do not write in any
files other than MP3 or WMA files or create any unnecessary folders.
Discs that contain a mixture of music data and MP3 or WMA format data cannot
be played.
●Extensions
If the file extensions .mp3 and .wma are used for files other than MP3 and WMA
files, they will be mistakenly recognized and played as MP3 and WMA files. This
may result in large amounts of interference and damage to the speakers.
●Playback
• To play MP3 files with steady sound quality, we recommend a fixed bit rate of 128 kbps and a sampling frequency of 44.1 kHz.
• CD-R or CD-RW playback may not be po ssible in some instances, depend-
ing on the characteristics of the disc.
• There is a wide variety of freeware and other encoding software for MP3 and WMA files on the market, and depend ing on the status of the encoding
and the file format, poor sound quality or noise at the start of playback may
result. In some cases, playback may not be possible at all.
• When files other than MP3 or WMA files are recorded on a disc, it may take
more time to recognize the disc and in some cases, playback may not be
possible at all.
