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

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, 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 can not correctly play back discs recorded
with Track At Once or packet writing.
• Order of tracks
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.
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.
