They're coming back.
Back with a vengeance.
185 terabytes of vengeance.
Way down deep in your hearts, you always knew they would...
Sony's technique, which will be discussed at today's International Magnetics Conference in Dresden, uses a vacuum-forming technique called sputter deposition to create a layer of magnetic crystals by shooting argon ions at a polymer film substrate. The crystals, measuring just 7.7 nanometers on average, pack together more densely than any other previous method.
The result: three Blu-Rays' worth of data can fit on one square inch of Sony's new wonder-tape.
Naturally, that kind of memory isn't going to go in the cassette deck on your ancient boom box any time soon. Sony developed the technology for long-term, industrial-sized data backup, a field where tape's slow write times and the time it takes to scroll through yards and yards of tape to find a single file aren't crippling problems.
