Level 1/Level 2, Joliet or Multi Session

1)

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 16 characters) make sure of 
the contents of the writing software, etc.

2) 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. This unit supports up to 
10 sessions.
CD-Extra: This format records audio (audio CD 
data) on the tracks in session 1 and data on the tracks 
in session 2.
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.

– a disc recorded with complicated tree 

structure.

– a disc recorded in Multi Session.

– a disc to which data can be added (non-
