Fujitsu is always talking up this or that hard drive technology that"s totally going to revolutionize the industry and so on, but at least this time around they"ve got some "solid" numbers.
Based on "areal density" technology, with Fujitsu claiming that a new vertical magnetic recording tech based on crystalline magnesium oxide allows them to sense even smaller magnetic pits, thereby allowing them to squeeze more data into each square inch. Fujitsu was promising 1TB per square inch a few months back, but it seems now they"ll settle for 500-800GB per square inch -- which translates to a roughly 500 percent capacity increase -- and should be shipping samples out in a couple years.
Start planning now how to best fill a 5TB drive.
