Files are played back
in
the order that the writing software writes
them to the disc. Therefore, the playback order may not be what
is
expected. Verify the writing order

RW
using
CO-R
writing software. A disc can hold up to 510 files/
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.

and CO-RWs.
Corresponding File Systems
This device supports discs formatted with IS09660 Level 1 or
Level
2.
Under the IS09660 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).
Bit rate
This is the "sound" compression rate specified
for
encoding. The
higher the bit rate, the higherthe sound quality, butalso 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, andother soundfiles into
the specified audio compressionformat.
