Methods of writing an audio CD
There are two ways in which you can write audio data to
CD-R/RW media.
● Track At Once
This method writes the data in units of CD tracks. The
advantage of this method is that you can add new
data to media that already contains existing data.
With the Track At Once method, the data from the
beginning to the end of the stereo track of a song is
written to the CD as one track. (Even if there is a por-
tion during the song that contains no data, it will be
written as silent audio data.)
Since each track is written individually when you use
this method, an interval of approximately two sec-
onds will be created between each track.
In order for a disc written using Track At Once to be
playable by the CD-RW drive or a CD player, you
must perform a process known as “finalizing” to
write track information to the disc. Once you have
finalized a disc, you cannot write any more data to it.
● Disc At Once
This method writes all tracks at once. Similarly to
when using the Track At Once method, the data from
the beginning to the end of the stereo track of each
song is written to the CD as one track.
However since writing does not stop until all data
has been written, there will be no gap between the
tracks.
When using Disc At Once to write a CD, you can use
the start point, end point and markers that were
assigned within the AW16G song to divide a single
continuous song into multiple tracks for writing.
For example, this is convenient when you have
recorded a live performance as a single song, and
want to assign track numbers while leaving the play-
back in continuous form.

Note
•A track shorter than four seconds cannot be written to
an audio CD. If you use start point/end point/markers
to divide a song into multiple tracks, make sure that
each track is at least four seconds long.
• If the length of the stereo track exceeds the writable
length of the media, you can create an audio CD by
adjusting the start point/end point so that the region is
within the allowable length. (

Media that you write using Disc At Once will be
finalized automatically, and can be played back by a
CD-RW drive or CD player that supports that type of
media. However, no further data can be written to a
disc that was written using Disc At Once.
