Recording MP3/WMA/AAC files on a CD-media
• You are recommended to minimize the chances of
making a disc that contains both CD-DA files and
MP3/WMA/AAC files.
• If CD-DA files are on the same disc as MP3, WMA
or AAC files, 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 files other than MP3/WMA/AAC files and
unnecessary folder on a disc.
• The name of an MP3/WMA/AAC 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", ".wma" or ".m4a" should be
assigned to each file depending on the file format.
