New Hard Drive Sizes Expand with Heat & Magnets


Having problems fitting your *ahem* “Nature” videos, games and music collection on your terabyte hard drive? Well, researchers plan to blow the ceiling off hard drive storage by combining heat and magnetism.

The researchers realized that using these two very different methods to store data you can achieve great things. Things like super-high capacity hard drives. This technology promises drives with one terabyte per square inch density with a potential of up to 10 terabytes per square inch.

Sure it’s all physics and formulas now but think about the future.¬† The new approach means that the 2.5″ hard drive in your laptop could¬† soon store more data than you could have imagined a few years ago at a fairly reasonable price. Also, it means we can keep up with the explosion of HD and super high quality digital video from our favorite “cinematic” pastimes.

Nature Photonics features a (really scientific) white paper that details the combination of thermally-assisted magnetic recording (TAR) using a plasmic antenna and the “magnetic islands” used in bit-patterned recording (BPR). These islands keep the data from bleeding together as a laser routed through the plasmic antenna heats them up allowing them to store more data. Yeah, I’m not sure what I just said either, but trust me on this.. it’s cool.

Now I can start to plan for the day when I can “archive” all my HD content and carry it around in my back pocket..
