Producing MP3/WMA discs
MP3/WMA files are prepared, then written to a CD-R or CD-RW
(DVD-R/DVD-RW) using CD-R writing software. A disc can hold
up to 1024 files/256 folders (including Root Folders).
Depending on the structure of the folders or files, it may take
time to read a disc. In this case, it is recommended to decrease
the number of folders or files.
Media supported
The media that this device can play back are CD-ROMs, CD-Rs
and CD-RWs.
Corresponding File Systems
This device supports discs formatted with ISO9660 Level 1 or
Level 2.
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).
This device also can play back discs in Joliet, etc., and other
standards that conform to ISO9660. However, sometimes the
file names, folder names, etc., are not displayed correctly.

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
The unit plays the files in the order that the writing software
writes them. Therefore, the playing order may not be the same
as the order you input. The playback order of the folders and
files is as follows. However, the folder and file playback order
differs from the folder no. and file no. indicated on the display.

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 files.
MP3: ID3 tag
WMA: WMA tag
Root folder
The root folder is found at the top of the file system. The root folder
contains all folders and files.
