Recording MP3/WMA 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 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.
¡ You may encounter trouble in playing MP3/WMA files
or displaying the information of MP3/WMA files
recorded with certain writing software or CD
recorders.

back will be played.
