What is MP3/WMA
MP3 is an audio compression method
and classified into audio layer 3 of MPEG
standards.
WMA is an audio compression method
developed by Microsoft Corporation.
These audio compression methods have
penetrated into PC users and become a
standard format.
These features compress the original audio
data to about 10 percent of its initial size with
a high sound quality. This means that about
10 music CDs can be recorded on a CD-R
disc or CD-RW disc to allow a long listening
time without having to change CDs.
Note: Some CDs recorded on CD-R/RW
mode may not be usable.
Displaying MP3/WMA TAG titles
Tag information such as title, artist and
album title can be displayed for MP3/WMA
file containing Tag information.

File extensions
1. Always add a file extension ".MP3",
".WMA" to MP3, WMA file by using single
byte letters. If you add a file extension
other than specified or forget to add the
file extension, the file cannot be played.
2. Files without MP3/WMA data will not play.
The files will be played soundlessly if you
attempt to play files without MP3/WMA
data.
* When VBR files are played, the play time
display may differ the play location.
* When MP3/WMA files are played, a little
no sound part is caused between tunes.
Logical format (File system)
When writing MP3/WMA file on a CD-R disc
or CD-RW disc, please select "ISO9660 level
1, 2 or Joliet or Romeo" or Apple ISO as the

be possible if the disc is recorded on another
format.
Folder structure
A disc with a folder having more than 8
hierarchical levels will be impossible.
Number of files or folders
1. Up to 999 files can be recognized per
folder.
Up to 6000 files can be played.
2. Tracks are played in the order that they
were recorded onto a disc. (Tracks
may not always be played in the order
displayed on the PC.)
3. Some noise may occur depending on
the type of encoder software used while
recording.
Playing MP3 folders
When selected for play, files and folders
(Folder Search, File Search or Folder Select)
are accessing in the order in which they were
written to the media.
As a result, the order in which they are
expected to be played may not match the
order in which they are actually played.
You may be able to set the order in which
MP3/WMA files are to be played by assigning
file names beginning with play sequence
numbers such as "01" to "99".
For example, a medium with the following
folder/file hierarchy is subject to Folder
Search, File Search or Folder Select.
