• You are recommended to minimize the chances of
making a disc that contains both CD-DA fi les and
MP3/WMA/AAC fi les.
• If CD-DA fi les are on the same disc as MP3, WMA
or AAC fi les, the songs may not play in the intended
order, or some songs may not play at all.
• When storing MP3 data, WMA data and AAC data on
the same disc, use different folders for each data.
• Do not record fi les other than MP3/WMA/AAC fi les and
unnecessary folder on a disc.
• The name of an MP3/WMA/AAC 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”, “.wma” or “.m4a” should be
assigned to each fi le depending on the fi le format.
• You may encounter trouble in playing MP3/WMA/AAC
fi les or displaying the information of MP3/WMA/AAC
fi les recorded with certain writing software or CD
recorders.
• This unit does not have a play list function.
• Although Multi-session recording is supported, the use
of Disc-at-Once is recommended.

What is MP3/WMA/AAC?
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 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.
AAC is an abbreviation for “Advanced Audio Coding”.
It has been defi ned as a standard for audio compression
technology using MPEG 2 and MPEG 4.
Note: MP3/WMA/AAC encoding and writing software is
not supplied with this unit.
Points to remember when making
MP3/WMA/AAC fi les
Common
• High bit rate and high sampling frequency are
recommended for high quality sounds.
• Selecting Variable Bit Rate (VBR) is not recommended
because playing time is not displayed properly and
sound may be skipped.
• Selecting Variable Bit Rate (VBR) is not recommended
because Re-master function may have little effect in
some cases.
• 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
• It is recommended to set the bit rate to “128 kbps or
more” and “fi xed”.
WMA
• It is recommended to set the bit rate to “64 kbps or
more” and “fi xed”.
• Do not set the copy protect attribute on the WMA fi le
to enable this unit to play back.
AAC
• It is recommended to set the bit rate to “128 kbps or
more” and “fi xed”.
• The formats and extensions for AAC data vary
according to the encoder software used.
• AAC fi les which can be played on this unit have the
“.m4a” extension and were encoded with Apple
iTunes

Caution
Never assign the “.mp3”, “.wma” or “.m4a”
