2.4 How to append audio or data to a disc
If a disc was not used to its full capacity the first time you recorded on it, and you did not close the disc
(see below), then you can add extra audio tracks or data sessions to the disc.
Closed session:
If you want to listen to an audio CD on a home or car CD player, you must close the session first. You
can put additional audio tracks on the disc afterwards, but only the tracks in the first session will be
accessible ("seen") by most CD players. Leaving the session open is only an option when writing
Audio. When writing data, the recording software will always automatically close the session.
Closed disc:
The user has the option to close the disc or not. The Close Disc option write-protects the CD. When
this operation has been performed, no more audio or data can be recorded to the CD.
Open disc:
1. Place the disc that has not been closed into the CD-ReWriter or DVD+RW drive.
2. Start the recording software.
3. Simply click the extra source material you want to record, and drag it from the Explorer window to
the CD Layout window to add it to the existing content.
4. Repeat this for each file and folder you want to record.
5. Finally, start the CD recording process.
