15.3.5 Disc At Once, Track At Once
Today, we differentiate between two different recording technologies
with CD-recorders: Disc At Once and Track At Once. Newer
recorders generally support both technologies, while older devices
frequently can only handle Track At Once.
For a recorder with Track At Once, every track is written separately.
Therefore, pauses are unavoidably created between the tracks
which cannot be influenced by the recording software. In contrast to
this, with Disc At Once, the entire CD is written in one procedure,
which allows more freedom for the recording software, but at the
same time prevents subsequent modifications. For many formats
(Audio-CD) Disc At Once is more logical, since unnecessary pauses
can be avoided, while Track At Once is generally used for multi-
session CDs.
15.4 Recording Formats
We will give you an overview of the most important recording
formats in the following sections.
15.4.1 Audio-CD
In 1980, the Audio-CD was the first medium for storing information
on a CD. The corresponding requirements are described in the Red
Book. All CD-ROM drives typically available in the marketplace can
also read Audio-CDs.
