If you print 8 dots (bits) in one square mm, that is one byte per square
mm. So 1 Meg requires one square metre, which is 16 A4 pages.
A Gigabyte needs 16000 A4 pages, and 100 Gig (a typical hard drive
today) needs 1,600,000 A4 pages.
So one DVD full needs a library shelf.
(Now somebody tell me I have slipped some decimal places!)
