The most common international standard for the

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.
