well the only thing that i know of is
Sony is coming out with Double density CD's
1.3 gigs per cd
even more Mp's now
i tink you need a new drive to read them.. since the pits are smaller
much smaller, half the size , a stronger laser
but nothing that holds more then 80 minuets, unless you overburn
which would only yeild a few more minuets.
some games a protected that way
