MP3 (MPEG audio layer 3) and WMA (Windows MediaTM 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 sin- gle CD media. (This figures refer to data recorded on a 650 MB

≥If |
WMA files, the songs may not play in the in- |
tended 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. |
≥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.
≥The file extension “.mp3” or “.wma” should be assigned to each file depending on the file format.
