The actual usable data capacity of the CD-ROM is spec'd around
750 Megabytes.  I could find out the exact number if I dug through
the pile on my desk to find the data sheets that came with the CD-ROM
test disc I have sitting here.  What Marty says about more errors
at the outer edge is definitely true--there is a premium charged
to the people who want to make CD music discs if they want to
run over 59:59 (by most manufacturers).  Of course, the reason you
don't find the errors on those long discs is the whole reason for the
premium you pay--they toss out the bad discs during testing.
