1)
When you load CD-ROM/CD-R/CD-RW discs, the
media disc’s status display may appear, the same as
that for playable discs, but there will be no sound.
2) ISO9660 Format
The most common international standard for the
logical format of files and folders on a CD-ROM.
There are several specification levels. In Level 1,
file names must be in the 8.3 format (no more than
eight characters in the name, no more than three
characters in the extension “.MP3”) and in capital
letters. Folder names can be no longer than eight
characters. There can be no more than eight nested
folder levels. Level 2 specifications allow file
names and folder names up to 31 characters long.
Each folder can have up to 8 trees.
For Joliet in the expansion format (file and folder
names can have up to 64 characters) make sure of
the contents of the writing software, etc.
3) Multi Session
This is a recording method that enables adding of
data using the Track-At-Once method.
Conventional CDs begin at a CD control area called
the Lead-in and end at an area called Lead-out. A
Multi Session CD is a CD having multiple sessions,
with each segment from Lead-in to Lead-out
regarded as a single session.
4) CD-Extra: This format records audio (audio CD
data) on the tracks in session 1 and data on the tracks
in session 2.
5)
Mixed CD: This format records data on the first
track and audio (audio CD data) on the second and
subsequent tracks of a session.
Notes on CD-R and CD-RW
• Some CD-Rs or CD-RWs cannot be played
on this system depending upon the recording
quality or physical condition of the disc, or
the characteristics of the recording device.
Furthermore, the disc will not play if it has not
been correctly finalized. For more
information, see the operating instructions for
the recording device.
• Discs recorded on CD-R/CD-RW drives may
not be played back because of scratches, dirt,
recording condition or the driver’s
characteristics.
• CD-R and CD-RW discs recorded in multi-
session that have not ended by “closing the
session” are not supported.
• The system may be unable to play MP3
format files that do not have the extension
“.MP3”.
• Attempting to play non-MP3 format files that
have the extension “.MP3” may result in noise
or malfunction.
• With formats other than ISO9660 level 1 and
2, folder names or file names may not be
displayed correctly.
• The following discs take a longer time to start
playback.
