The November 17,1999 edition of the Globe and Mail had an interesting article on a new 3-dimensional optical storage technology, which promises to offer 10,000 gigabytes (10 terabytes!) in a cubic centimeter. Currently a U. of T. group has produced a working model which packs 1,000 gigs of write-only memory in a cube. They are working to up this by a factor of ten, and also plan to upgrade to read/write memory. I would have guessed we might have to wait for 50 years for this kind of memory storage. It now looks it could be available in as little as 5 years!
