 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.
+.PP
+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.
