MP3

and WMA files

• MP3 is short for MPEG Audio Layer 3 and

refers to an audio compression technology
standard.

• WMA is short for Windows Media™ Audio and

refers to an audio compression technology
that is developed by Microsoft Corporation.
WMA data can be encoded by using Windows
Media Player version 7, 7.1 or Windows
Media Player for Windows XP.

• Depending on the application which has per-

formed the encoding of the WMA files, the
operation may not be normal.

• Depending on the application which has per-

formed the encoding of the WMA files, the dis-
play of the album name and other character
information may not be normal.

• This product allows playback of MP3/WMA

files on CD-ROM, CD-R and CD-RW discs.
Disc recordings compatible with level 1 and
level 2 of ISO9660 and with the Romeo and
Joliet file system can be played back.

• It is possible to play back multi-session com-

patible recorded discs.

• MP3/WMA files are not compatible with pack-

et write data transfer.

• The max. number of characters which can be

displayed for a file name, including the exten-
sion (.mp3 or .wma), is 32 characters from the
first character.

• The max. number of characters which can be

displayed for a folder name is 32 characters.

• In case of files recorded according to the

Romeo and Joliet file system, only the first 32
characters can be displayed.

• When playing discs with MP3/WMA files and

audio data (CD-DA) such as CD-EXTRA and
MIXED-MODE CD, both types can be played
only by switching mode between MP3/WMA
and CD-DA.

• The folder selection sequence for playback

and other operations becomes the writing
sequence used by the writing software. For
this reason, the expected sequence at the
time of playback may not coincide with the
actual playback sequence. However, there
also is some writing software which permits
setting of the playback order.

Precaution:
• When naming an MP3 or a WMA file, add the corre-

sponding filename extension (.mp3 or .wma).

• This product plays back files with the filename

extension (.mp3 or .wma) as an MP3 or a WMA file.
To prevent noise and malfunctions, do not use
these extensions for files other than MP3 or WMA
files.
