If CD-DA fi les are on the same disc as MP3 or WMA

fi les, 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 fi les other than MP3/WMA fi les and

unnecessary folder on a disc.

• The name of an MP3/WMA fi le should be added by

rules as shown in the following descriptions and also
comply with the rules of each fi le system.

• The fi le extension “.mp3” or “.wma” should be

fi les or displaying the information of MP3/WMA
fi les recorded with certain writing software or CD
recorders.

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 fi gures refer to data recorded on
a 650 MB CD-R or CD-RW at a fi xed bit rate of 128 kbps
and a sampling frequency of 44.1 kHz).

MPEG Layer-3 audio coding technology licensed from
Fraunhofer IIS and Thomson.

Note: MP3/WMA encoding and writing software is not
supplied with this unit.

Points to Remember When Making MP3/WMA Files

recommended for high quality sounds.

• Selecting Variable Bit Rate (VBR) is not recommended

sound may be skipped.

• The playback sound quality differs depending on

the encoding circumstances. For details, refer to
the instructions of your own encoding software and
writing software.

MP3

more” and “fi xed”.
