Notes on MP3/WMA
E N G L I S H
What is MP3/WMA?
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 single CD media (This figures refer to data recorded on a 650 MB CD-R or CD-RW at a fixed bit rate of 128 kbps and a sampling frequency of 44.1 kHz). Note: ¡MP3/WMA encoding and writing software is not supplied with this unit. ¡CD writing software is not supplied with this unit.
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 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. ¡The file extension �.mp3� or �.wma� should be assigned to each file depending on the file format. ¡This unit does not have the play list function. ¡Although Multi-session recording is supported, the use of Disc-at-Once is recommended.

Points to remember when making MP3/WMA files
Common
¡High bit rate and high sampling frequency are recommended for high quality sounds. ¡Selecting VBR (Variable Bit Rate) is not recommended because playing time is not displayed properly and sound may be skipped. ¡The playback sound quality differs depending on the encoding circumstances. For details, refer to the user manual of your own encoding software and writing software.
MP3
¡It is recommended to set the bit rate to �128 kbps or more� and �fixed�.
WMA
¡It is recommended to set the bit rate to �64 kbps or more� and �fixed�. ¡Do not set the copy protect attribute on the WMA file to enable this unit to play back. ¡WMA Version 9 is supported. However, the new functions in Version 9 (WMA pro, Loss-less and the combination of 64 kbps and 45 kHz) are excluded.
