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?
Data transmission records were just made to be shattered, as we've seen the benchmark go from 2.56- to 14- and now to 25.6-terabits per second within a year (and five days, but who's counting?). The momentary record holder this time around is Alcatel-Lucent, which "successfully transmitted a world record 25.6Tbps of optical data over a single fiber strand' using 160 WDM channels. In case you were wondering, that's enough speed to send about 600 DVDs worth of information to your buddy in one single second, after which you'd likely destroy any and all functionality his / her computer previously had before the bombardment. Now, what's it cost to run one or two of these pipes to Sealand?
