ID3 tags/WMA tags
If tag data is in an MP3/WMA/AAC file, this device can display 
the title (track title), artist name, and album name ID3 tag/WMA 
tag data (maximum 128 characters).
This device can only display single-byte alphanumeric 
characters and the underscore. For non-supported characters, 
“NO SUPPORT” is displayed.
The number of characters may be limited, or not correctly 
displayed, depending on the tag information.
Playing back MP3/WMA/AAC 
MP3/WMA/AAC files are prepared, then written to a CD-R, 
 
CD-RW (DVD-R/DVD-RW) using CD-R writing software. A disc 
can hold up to 1024 files/256 folders (including Root Folders), 
and the maximum number of folders is 255. Playback may not 
be performed if a disc exceeds the limitations described above.
Media supported
The media that this device can play back are CD-ROMs, CD-Rs, 
and CD-RWs, DVD-Rs and DVD-RWs.
Corresponding File Systems
This device supports discs formatted with ISO9660 Level 1 or 
Level 2.
This device can play back discs in Joliet, Romeo, etc., and other 
standards that conform to ISO9660. However, sometimes the file 
names, folder names, etc., are not displayed correctly.
Formats supported
This device supports CD-ROM XA, Mixed Mode CD, Enhanced 
CD (CD-Extra) and Multi-Session.
This device cannot correctly play back discs recorded with 
Track At Once or packet writing.
Order of files
Files are played back in the order that the writing software writes 
them to the disc. Therefore, the playback order may not be 
what’s expected. Verity the writing order in the software’s 
documentation. The playback order of the folders and files is as 
follows. (The following numbers may differ from actually 
displayed numbers.)
Terminology
Bit rate
This is the “sound” compression rate specified for encoding. The 
higher the bit rate, the higher the sound quality, but also the larger 
the files.
Sampling rate
This value shows how many times per second the data is sampled 
(recorded). For example, music CDs use a sampling rate of 44.1 kHz, 
so the sound is sampled (recorded) 44,100 times per second. The 
higher the sampling rate, the higher the sound quality, but also the 
larger the volume of data.
Encoding
Converting music CDs, WAVE (AIFF) files, and other sound files into 
the specified audio compression format.
Tag
Song information such as track titles, artist names, album names, 
etc., written into MP3/WMA/AAC files.
Root folder
The root folder (or root directory) is found at the top of the file 
system. The root folder contains all folders and files. It is created 
automatically for all burned discs.
Under the ISO9660 standard, there are some restrictions to 
remember.
The maximum nested folder depth is 8 (including the root 
directory). The number of characters for a folder/file name is 
limited.
Valid characters for folder/file names are letters A-Z (all caps), 
numbers 0-9, and ‘_’ (underscore).
