Overburning is an old way of protecting a CD from being duplicated.
Some companies burned more than 650Mb onto their CD-ROM's and the
usual CD Recorders refuse to burn more than 650Mb. The problem was
solved with CD-R's of 80min and CD Recorders that were capable of
recording that amount of information.
Another strategy for solving the problem consists of burning onto a
normal (74min.) CD-R more than 650Mb since CD-R's include extra-space:
the nominal capacity is the amount of Mb that can be burned without
any risk (e.g. 656Mb) while the maximal capacity (e.g. 775Mb) is the
nominal capacity plus the extra Mb's included in the CD-R to ensure
that no risk exists when burning data up to the nominal capacity
(remember that tapes always include some extra minutes). This is
called overburning.
Some programs (I only know CD-R Identifier for Windoze) gives the
nominal and maximal capacity of your CD-R's. Thus, you can know how
much overburning can be done.
All you need is a CD Recorder which supports overburning and a CD-R with
more that 650Mb. You can not burn over the maximal capacity, and burning
over the nominal capacity is a risk.

I think there's no problem with that. 80min. CD-R's can not work with
all readers.
