Random Packet Write
A writing process where small amounts of data can be written and deleted in one action.
This writing method allows disc space to be used more efficiently when burning data
onto the disc. It allows data to be written onto the disc in the same way as the hard
disk, freeing disc space as data are deleted and reusing freed space.
Raw Mode
A disc writing process which reads and writes data as is. In this mode, the disc burner
does not correct or repair errors before burning data onto the disc. If this method is
used, errors on the original source will also be present on the disc.
Restricted Overwrite
A writing method for DVD-RW that allows random overwriting of data. This method can
only be used on pre-formatted DVD-RW discs.
Session-At-Once
A method that writes data in one uninterrupted sequence, that is, by session. A session
is an area on the disc that contains one or more tracks depending on the amount of data
burnt at a time. This writing method always closes each session but leaves the disc
open.
Session
A collection of one or more tracks. In CD disc, each recording process generates a
session containing all the tracks recorded at that time. A CD recorded in multiple
recording sessions is known as a multi-session CD. In DVD disc, there is only one
session in the disc.
Span disc
A feature that arranges files into multiple discs when the total size of a compilation
exceeds the capacity of the current disc.
Test Write
A simulation of the burning process before actually writing data to the disc.
Track-At-Once
A writing mode that writes data to a disc by track. When burning a disc in this mode, the
burner's laser turns on and off in between tracks, creating a gap between tracks. (This is
equivalent to two-second gaps of silence between audio tracks on an Audio CD.)
