13. Super Audio Cd
Separate Space for Multi=Track Recordings and Extra Data
The Super Audio CD is standardized, with disc space reserved for multi-channel recordings of up to six tracks,
extra data and audio signals, including conventional 2-channel stereo recordings. In short, allocated disc space
ensures that Super Audio CD will be able to handle all future applications. The disc space reserved for multi-
channel data includes high-quality multi-track audio recorded in DSD, for an auditory experience never before
possible. The space for extra data can be used to include text, song lyrics, liner notes and even still images (see
Figure 13-10). Both of these areas will be used in Super Audio CDs of the near future.

When a disc is inserted in the player, disc information that has been recorded in the Master Table of Contents
(TOC) is automatically read. This Master TOC contains information regarding the disc and artist. There is also
an Area TOC for each section of a Super Audio CD 2-channel, multi-channel and extra data. Each Area TOC
contains recorded information about the tracks included in that particular section. Thanks to the combination of
these two, player-side operation and track access become very simple. With Super Audio CD, disc title, track
title and artiste information, for example, can be easily displayed on the player, very similar to the CD TEXT
feature with conventional CD.
Up to 24 Music Titles and More
With Super Audio CD, it is possible to record and index up to 255 separate tracks, a considerable improvement
over CD format's 99 track limit. With Super Audio CD, it also becomes possible to produce recordings like a 200-
track Best of Classical, for example, or even language education software that features flexible access. Super
Audio CD was designed with future applications in mind, surpassing conventional CD standard for TOC and
track configuration.
Copyright Protection
Current audio systems protect against illegal copyright infringements by incorporating the Serial Copy Management
System (SCMS) on the hardware side. Super Audio CD features high capacity and therefore carries a high value
as a software asset, necessitating an effective copyright protection system. Super Audio CD, therefore,
incorporates copyright protection technology not only on the hardware side, but also on the disc itself to prevent
illegal copying of protected property.
