Table of Contents
(Universal Term - CDs) Usually known as TOC. On every CD, the first part of the disc (the section nearest
the hole in the middle) is the table of contents. This contains information such as how many tracks are on the
disc, how long each track is, how long the disc is etc. This information is required by the CD player in order
