The manufacturing cost would be higher and/or the pressing plant couldn't
offer the same guarantees if you want to press a disc longer than 74
minutes. The percentage of rejects goes up, because it is more difficult
to keep the outer edges of the discs uniform enough. However, as with
everything else related to CDs, they are getting better at it. The
absolute limit is about 80 minutes.
Normal CD-Rs can hold a few seconds more than 74 minutes. Ones which hold
more are available at a significant premium and they are not a common
sight.
My understanding is conductor Herbert von Karajan was asked how much music
a CD should hold. He thought a performance of Beethoven's Symphony No. 9
should fit on a single CD. (He might have had a particular performance in
mind. If so, probably one in which they did not do the repeat in the 4th
movement I think it is.)
One for the FAQ if it isn't in there already. And if there is a FAQ at
all...? (Yeah, I know, check the FAQ for the answer... :-)
