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. > > Will the overburnt CD work with all readers ? I think there's no problem with that. 80min. CD-R's can not work with all readers. -- Santi
