Doing some math, calculating the area of a DVD's surface based on the fact

there is a 4.4cm diameter in the center that is unrecordable, and there is

0.2cm on each side that is unrecordable and that they are 12cm in diameter,

and assuming those unrecordable areas were to remain constant in a 12" disc

(LD or LP size), I found that the recordable area of a 5" disc is 40.715

square cm. If these discs were to be 12" they would contain a whopping

517.94 square cm of recordable area.

Just assuming that if these 40.715 cm² can hold 4.7GB, then it would stand

to reason that 517.94 cm² can hold 59.8GB. But, since 4.7GB isnt real GB

but rather 4.38GB, then this 59.8GB is really 55.7GB. Alright, so 55.7GB on

1 layer. If its dual layer, like the 8.5GB discs that could be released

this summer, then you have 108GB.

How much can 55.7GB hold?

Well, I found out how big the main movie was on each of 15 random discs I

have and compared that to the length of the movie. The result, there are

approximatley 37.61MB used for each minute of movie. In a 55.7GB disc, it

would then stand to reason that if the quality is kept like it is now, then

1517 minutes could fit on a disc. That's a little more than 25 hours. Now,

if the discs have 2 layers, then they hold about 2940 minutes, or 49 hours.

Wow, I'm so glad that nobody has made a movie that needs a disc that large.

Although, if you had one you could put all of the LOTR movies on there. Or

all the Godfathers. Or any other trilogy you can think of. Maybe James

Bond would need one of them dual layer discs, though

How about series?

You could fit the first 2 seasons of the Sopranos on 1 single layer disc.

Or you can fit all 4 seasons on 1 dual layer disc. How many Simpsons

episodes is that? Wow, thats a lot, 133 episodes or so. I believe that

works out to 6 seasons, since the first year was short.

Nah, I much prefer the convenience of 5" discs, though. If it wasnt for the

CD, our DVDs could have been based on LDs, though, since that was the only

other optical media and came well before CD.

Then again, the covers for these discs would have some really nice artwork.

That is one thing I liked about real albums...much more space for artwork.
