What is MP3IWMA?
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 CO-R disc or CO-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 MP3IWMA TAG titles
Tag information such as title, artist and album
title can be displayed for MP3IWMA file
containing Tag information.
Precautions when creating an MP3 disc
• File extensions
1. Always add a file extension ".MP3" or ".mp3"
to an MP3 file, and ".WMA" or ".wma" to a
WMA file by using single byte letters. If you
add a file extension other than specified or
forget to add these file extension, the file
cannot be played. In addition, if you use upper
case and lower case letters (capital and small
letters) mixedly for file extensions, normal
play may not be possible.
2. Files other than MP3IWMA data cannot be
played.
Playing files with a format not supported will
be skipped, and the scan, random and repeat
playback mode may be canceled.

not supported: *.AAC, *.OLF, *.M3U, *.PLS,
MP3 PRO files, files with DRM, open session

• Logical format (File system)
1. When writing an MP3IWMA file on a disc
please select "1509660 level 1 or level
2
(without including expansion format)" as
the writing software format. Normal playback
may not be possible if the disc is recorded on
another format.
2. The folder name and file name can be
displayed as the title during MP3IWMA play
but the title must be within 31 single byte
alphabetical letters and numerals for the
folder name and file name (including an
extension). Entering more letters or numerals
than specified may cause an incorrect
display.
• Entering File and Folder Names
Names using the code list characters are the
only file names and folder names that can be
entered and displayed. Using any other
charac~er
will cause the file and folder names
to be displayed incorrectly.
• Electronic Shock Protection
10 seconds for CO-OA (COA)
45 seconds for MP3 recorded at 44.1 kHz,

• Folder structure
1. A disc with a folder having more than 8
hierarchical levels will conflict with the
IS09660 and playback will be impossible.
• Number of files or folders
1. The maximum allowable number of folders is
255 (including root directory); the maximum
allowable number of files is 512 (max. 255 per

of tracks that can be played back.
2. Tracks are played in the order that they were
recorded onto a disc. (Tracks might not
always be played in the order displayed on
the PC).
• Some noise may occur depending on the
type of encoder software used while
recording.
• In case of a track recorded at VBR (variable
bit rate), the display for the play time of the
track may be slightly different from the
actual play time. Also, the recommended
value of VBR ranges from 32 kbps to
320 kbps.
• After disc selection, the play mode is
