There can be more than one track burned by a single run of cdrskin.
|
||||
CDs can be kept appendable so that further tracks can
|
||||
be witten to them in subsequent runs of cdrskin (see option -multi).
|
||||
be written to them in subsequent runs of cdrskin (see option -multi).
|
||||
Info about the addresses of burned tracks is kept in a table of
|

content (TOC) on media and can be retrieved via cdrskin option -toc.
|
||||
These informations are also used by the operating systems' CD-ROM read drivers.

In general there are two types of tracks: data and audio. They differ in
|
||||
sector size, throughput and readability via the systems' CD-ROM drivers
|
||||
resp. by music CD players.
|
||||
.br
|
||||
If not explicitely option -audio is given, then any track is burned as data
|
||||
unless the track source is a file with suffix ".wav" or ".au" and has a
|
||||
header part which identifies it as MS-WAVE resp. SUN Audio with suitable
|
||||
parameters. Such files are burned as audio tracks by default.
|
||||
.PP
|
||||
While audio tracks just contain a given time span of acoustic vibrations,
|
||||
data tracks may have an arbitray meaning. Nevertheless, ISO-9660 filesystems
|
||||
are established as a format which can represent a tree of directories and
|
||||
data files on all major operating systems. Such filesystem images can be
|
||||
produced by programs mkisofs or genisoimage. They can also be extended by
|
||||
follow-up tracks if prepared properly. See the man pages of said programs.
|
||||
cdrskin is able to fulfill the needs about their option -C.
|
||||
.br
|
||||
Another type of data track content are archive formats which originally
|
||||
have been developed for magnetic tapes. Only formats which mark a detectable
|
||||
end-of-archive in their data are suitable with CD, though. Well tested are
|
||||
the archivers afio and star. Not suitable seems GNU tar.
