Definition of Disc-At-Once
Disc-At-Once
Definition: In Disc-at-Once mode, the whole disc is written without turning off the recording laser. All of the information to be recorded needs to be staged on the computer's hard disk prior to recording. The mode is especially useful for creating a master disc for subsequent mass production via a replicator since 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 mastering process. It requires the pre-mastering software to send a "cue sheet" to the CD-R/DVD-R drive that describes the disc layout.
