A few years back I read a facinating article on
holographic storage systems.
Where the medium was a 'slide sized' wafer and was recorded and read
holographically using a laser beam. Being holographic in nature the denisty
was way more then magnetic disc or CD. That was the closest that I've read to
Star Trek like storage.
This article was in a special topic issue of Scientific American, on the
future of information technology. About 3 yrs ago I think. All the
articles were good.
