Making and playing MP3/WMA files
MP3/WMA files created by recording broadcasts, records, audio recordings, video 
recordings or live performances cannot be used for purposes other than personal 
entertainment without permission of the copyright holder as set forth in copyright law.
There are many kinds of sites that distribute MP3/WMA files on the Internet, such as "pay per 
download" online shopping sites, "try before you buy" listening sites and free download sites.  
Follow the rules for each site (such as paying fees) and download according to site 
instructions.
Prepare a computer with commercially available MP3/WMA encoding software (conversion 
software).  Some encoding programs available on the Internet do not require payment.  
Music data files in MP3/WMA format can be made by inserting the music CD into the CD-
ROM drive of the computer and following the procedures of the MP3/WMA encoding software 
to compress the songs of the music CD.  A 12cm music CD (having a maximum of 74 
minutes of recording/650MB of data) can be compressed to 65MB (about 1/10 of the original 
size).
MP3/WMA files can be recorded on CD-R/RW by using a CD-R/RW drive connected to a 
computer.  Record by setting the recording format of the recording software to ISO9660 level 
1 or level 2 (not including extension format).
Select CD-ROM ( mode1 ) or CD-ROM XA ( mode2 ) for the disc format.
Insert a CD-R/RW disc having recorded MP3/WMA files.  The system will automatically 
determine whether the disc is a music CD or a CD-R/RW with MP3/WMA files and begin 
playing the disc.  A music CD recorded onto a CD-R/RW can also be played.  However, 
depending on the type of disc being used, the disc may not play.

Converting CD music to MP3/WMA files
Writing to CD-R/CD-RW
When playing back CD-R/RW
• A fixed bit rate of 128kbps and sampling frequency of 44.1kHz is recommended 
for obtaining stable audio quality at playback.
• Depending on the characteristics of a disc, CD-R and CD-RW may not be able 
to read the disc.
• Because there are many types of MP3/WMA encoding software available, 
including commercial and freeware programs, audio quality may deteriorate, 
noise may be generated when playing starts and some recordings may not play, 
depending on the condition of the encoder and the file format.
• When files other than MP3/WMA files are recorded on a disc, the system may 
take some time to recognize the disc and it may not play the disc.
