ISO 9660 format
This is 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 8 characters in the
name, no more than 3 characters in the
extension "MP3") and in capital letters.
Folder names can be no longer than
8 characters. There can be no more
than 8 folder levels (trees). Level 2
specifications allow file names up to 31
characters long.
Each folder can have up to 8 trees.
For Juliet or Romeo in the expansion
format, please consider these
restrictions when configuring your CD
writing software.
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.

Mixed CD: In this format, data is
recorded as track 1, and audio
(audio CD data) is recorded as track
2.
With formats other than ISO 9660
level 1 and level 2, folder names or
file names may not be displayed
correctly.
When naming, be sure to add the
file extension ".MP3" to the file
name.
If you put the extension ".MP3" to a
file other than MP3, the unit cannot
recognize the file properly and will
generate random noise that could
damage your speakers.
The following discs take a longer
time to start playback.
•
a disc recorded with
complicated tree structure.
•
a disc recorded in Multi Session.
•
a non-finalised disc to which
data can be added.
If an MP3 file is in the disc, only MP3
file(s) play back and other data
is skipped. (Audio CD data is not
recognised.)
