Track At Once and Disc At Once
Data can be written to CD-R/RW media in one of the following two ways.
❍ Track At Once
In this method, data is written in units of tracks (individual regions of audio data).
This method can be used only for CD-R media.
When the Track At Once method is used to write data to a CD-R, approximately
two seconds of silence will be created between tracks each time a track is writ-
ten. Additional audio data can be recorded later on CD-R media that was written
using this method.
• In order for CD-R media written using Track At Once to be played on a CD-RW
drive or on a conventional CD player, you must perform the Finalize operation
to write track location data etc. on the disc after all tracks have been written.
• No further recording is possible on CD-R media that has been finalized.
❍ Disc At Once
This method writes the data for all tracks in one operation, and can be used for
either CD-R or CD-RW media. Unlike the Track At Once method, the operation
will not stop until all data has been written, meaning that there will be no silent
sections between tracks.
• CD-R/CD-RW media written using Disc At Once will automatically be final-
ized, and can therefore be played immediately on a CD player.
• No further data can be recorded on media written using Disc At Once. (How-
ever in the case of CD-RW media, you can erase all of the audio data and then
rewrite.)
