Fujitsu achieves another storage milestone using patterned media technology
_______________________________________________________

Although it seemed that Seagate was comfortably at the forefront of magnetic recording developments, Fujitsu is hoping that its latest "breakthrough" will add a little friction to the areal density competition. Using patterned media technology, the firm "was able to achieve a one-dimensional array nanohole pattern with an unprecedented 25 nanometer pitch," which essentially means that recording one-terabit per square inch onto HDDs of the future is now realizable. Additionally, the company also revealed a new development "involving perpendicular magnetic recording (PMR) read / write operation on random patterned media," which utilizes the soft underlayer (SUL) as the PMR media. As expected, the presenters weren't as forthcoming about when we'd actually see these achievements make a difference in our laptops, servers, and other HDD-equipped devices, but the sooner the better, okay Fujitsu?
