Computer researchers are always vying to cram just a little more information into a slightly smaller space. But a new technology just announced by scientists at AT&T Bell Laboratories may force the competition into playing catch-up for a long time to come. They have found a way to squeeze up to 45 billion bits of data onto a square inch of disk space -- 300 times as much as an ordinary disk, and 100 times as much as the most advanced magneto-optical technology. The system could put two copies of War and Peace on the head of a pin.
