There are six basic editing functions possible on MDs, as

•
Track erase function (for erasing specific tracks)
An entire track, from beginning to end, can be erased
instantaneously simply by operating buttons. Unlike tapes,
there is no need to record over, erase, or cut the tape.
•
Cue erase function (erasing cue signals)
Cue signals (external control signals) recorded on the disc can
be erased without affecting the tracks.
•
A-B erase function (for erasing any section)
Sections can be selected directly and erased, without using the
divide or combine function.
•
Undo functions (for undoing the editing)
Even after editing is completed, the editing can be undone as
long as the UTOC has not yet been written.
There are three types of undo functions:
1) UNDO: For undoing the last editing operation.
2) REDO:
For resetting the editing undone with the undo
function.
3) FIRST: For undoing all the editing operations.
