Sector
A sector is the smallest addressable information unit of a CD.
It is composed of 2352 bytes of which - depending on the type
of CD used - differing amounts are available as user data. A
sector generally consists of a header, synchronization bits and
user data. It may also have error recognition and correction
data. To read a sector, a drive with simple reading speed
requires 1/75th of a second.
Session
An inter-related writing procedure is defined as a session. A
session consists of the Lead In area, the data area, and the
Lead Out area. A CD can be written with several sessions.
This is then called a multi-session CD, in contrast to a single-
session CD which only contains one session. A silver CD
generally consists of one session.
Simulated Recording
Simulation of the burn process in order to test whether there is
a constant writing flow. The procedure is the same as the
writing of the CD, with the only difference being that the laser
writer is switched off.
TOC
Table of Contents. This designates the contents of every
session and is stored in the Lead In.
Track
In an Audio-CD, one track corresponds to one piece of music.
With a CD-ROM, one track contains computer data and it may
have any number of files and folders.
Volume Descriptor
The Volume Descriptor is the area at the beginning of a CD in
which the structure of the file system is contained. It may also
contain additional and optional information about the CD, such
as the name of the CD, the publisher, a copyright notice, etc.
