WHAT IS “DISC AT ONCE”?
• Disc at Once is a writing mode that requires data to be
written continuously, without any interruptions, until the
entire data set is transferred to the CD-R.
• The lead-in, program and lead-out are written in a single
event. All of the information to be recorded needs to be
staged on the computer’s hard disc prior to recording in
the Disc at Once mode.
• This mode is usually preferred for discs that are sent to a
CD-ROM replication facility when CD-R is the source
media.
• Recording in the Disc at Once mode eliminates the
linking and run-in and run-out blocks associated with
multisession and packet recording modes, which often are
interpreted as uncorrectable errors during the glass
mastering process.
WHAT IS “TRACK AT ONCE”?
• Track at Once is a writing mode that allows a session to
be written in a number of discrete write events, called
tracks.
• The disc may be removed from the writer and read in
another writer (given proper software) before the session
is fixated.
The written sessions contain complete “tracks” of information.
WHAT IS “INCREMENTAL” OR “PACKET” WRITING?
• Track at Once writing is a form of incremental write
which mandates a minimum track length of 300 blocks
and a maximum of 99 tracks per disc.
