Red book audio is also referred to as CD-DA (Compact
Disc-Digital Audio). Introduced by Sony and Philips
in 1980, the Red Book standard was simply designed to
be a universal medium for distributing digitized music.
Data on a audio CD is organized
into frames. Each frame contains up to 24 bytes of user
data, synchronization, LECC (Logical Error Correction
Code), and data for control and display. Frame are interleaved
with other frames into a single, spiral so that scratches
or defects will not destroy a single frame beyond correction.
Rather, a scratch will destroy a small portion of many
frames, all of which can be recovered in other frames.
A Red Book disc is divided into
three areas: Lead In, Program, and Lead Out. Every track's
location is recorded into the disc's TOC (Table of Contents)
which is stored in the Lead In area of every disc. The
Red Book CD was to become the template for which all
other "book standards" were created.
