MP3/WMA Player
¡
You are recommended to minimize the chances of

MP3/WMA files.
¡
If CD-DA files are on the same disc as MP3 or WMA
files, the songs may not play in the intended order,
or some songs may not play at all.
¡
When storing MP3 data and WMA data on the same
disc, use different folders for each data.
¡
Do not record files other than MP3/WMA files and
unnecessary folder on a disc.
¡
The name of an MP3/WMA file should be added by
rules as shown in the following descriptions and also
comply with the rules of each file system.
¡
The file extension “.mp3” or “.wma” should be

What is MP3/WMA?
MP3 (MPEG Audio Layer-3) and WMA (Windows Media
TM
Audio) are the compression formats of digital audio. The
former is developed by MPEG (Motion Picture Experts
Group), and the latter is developed by Microsoft
Corporation. Using these compression formats, you can
record the contents of about 10 music CDs on a single
CD media (This figures refer to data recorded on a 650
MB CD-R or CD-RW at a fixed bit rate of 128 kbps and a
sampling frequency of 44.1 kHz).
Notes:
¡
MP3/WMA encoding and writing software is not sup-
plied with this unit.
¡
CD writing software is not supplied with this unit.

sound may be skipped.
¡
The playback sound quality differs depending on the
encoding circumstances. For details, refer to the user
manual of your own encoding software and writing
software.
