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 disk prior to recording in the Disc at Once mode. This mode is used to eliminate the two second gap between tracks when recording audio.
