• A track written “at once” has 150 blocks of overhead for
run-in, run-out, pre-gap and linking. Packet write, on the
other hand, is a method whereby several write events are
allowed within a track, thus reducing the overhead.
These “packets” are bounded by 7 blocks for run-in (4), run-out
(2) and link (1).
WHAT’S THE DIFFERENCE BETWEEN A “MULTISESSION”
DISC AND A “MULTITRACK” DISC?
• A “session” is a unity on a CD which is bounded by
lead-in and lead-out. A session contains one or several
(up to 99 per disc) tracks.
• There are two types of tracks. A Red Book audio track is
usually written in disc at once mode along with several
other tracks in one session.
These tracks have index numbers in the subchannel
which differentiate one from the other and which allow
selective playback.
• The other type of track is the incrementally written type
described above.
