CD-RW using CD-R writing software. Each disc
can hold up to 255 files/folders (including Root
Folders).
• 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.

• When CD audio and MP3 files are both present
on a disk, playback starts from Folder No. 2.
Also, the track display for CD audio data playback
is the track numbers recorded on the disc.
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 level 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.
ID3 tag
Song information such as track titles, artist
names, album names, etc., written into MP3 files.
