Page "CD-R" Paragraph 9

Despite the foregoing, most CD-Rs on the market have an 80 minute capacity.

There are also 90 minute / 790 MB and 99 minute / 870 MB discs, although they are less common ( and depart from the Orange Book standard outright ).

Also, due to the limitations of the data structures in the ATIP ( see below ), 90 and 99 minute blanks will identify as 80 minute ones.

( As the ATIP is part of the Orange Book standard, it is natural that its design does not support some nonstandard disc configurations.

) Therefore, in order to use the additional capacity, these discs have to be burned using " overburn " options in the CD recording software.

( Overburning itself is so named because it is outside the written standards, but, due to market demand, it has nonetheless become a de facto standard function in most CD writing drives and software for them.
