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) 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.

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.
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.
