Media
Media such as CD-R and CD-RW
discs are capable of playing MP3/
WMA files. Compared to the
CD-ROM media commonly used for
music discs, CD-R and CD-RW
discs are easily damaged in high
temperature/high humidity
environments and part of the CD-R
and CD-RW may become incapable
of playback. Fingerprints or
scratches on the disc may prevent
playback or cause skipping during
playback. Sections of a CD-R or
CD-RW may deteriorate if it is left
inside a vehicle for long periods of
time. It is also recommended that
CD-R and CD-RW discs be kept in
a light-resistant case because the
discs are vulnerable to ultra-violet
light.
Format of Discs
The format of discs to be used must
be ISO 9660 Level 1 or Level 2.
Control items for this standard are
as follows:
Maximum directory layers:
8 layers
Maximum characters for folder
names/file names: 48 (including
_ and 3 letter file extension)
Maximum number of folders:
192 (including the root folder)
Maximum number of files per
disc: 255
A root directory is counted as one
folder.
File Names
Only files with the MP3/WMA file
extension mp3, .wma can be
recognized as MP3/WMA and
played. Be sure to save MP3 files
