Session at Once (SAO)
– A CD writing process which is similar to DAO, where all of the information is written in one ses-
sion, but SAO allows for the ability to begin another session and record at a later time. This mode allows for greater control
of the recording process than PW or TAO, and more disc space can be utilized because there is no need for gaps between
tracks.
Track at Once (TAO)
– A CD writing process where data is added one track at a time, and the data can be added at a
later time. The CD being written to, though, can only be read in the CD rewritable drive that is recording it until the disc is
finalized (meaning that no more data can be added). There is also a gap of 2 seconds added between tracks, which will be
heard as noise in some audio players.

Technical noTe:
*Buffer Underrun
– The recording of a disc is a system-intensive application, and the rewritable
drive needs a constant stream of data. A buffer underrun occurs when the stream of data to the rewritable drive is not
fast enough to keep the rewritable drive’s buffer full, causing the an error in the recording process. If this problem oc-
curs often, turn down the recording speed and consult section 4.1 Advice for Optimizing FireWire Connections.
