Researchers create a tiny ‘Atomic’ hard drive that can store 500 terabits of data

in #tech8 years ago

 Imagine if individual atoms could store data. Dutch researchers are  working on doing just that, and can fit 500 terabits of data in a single  square inch. That’s right: 500 terabits, or 62.5 terabytes, in a drive  the size of a postage stamp. This atomic hard drive is 500 times more dense than current  solid-state drives, but don’t look for it on the market anytime soon.  You can, however, read about it in a paper published in Nature Nonotechnology, if you’re up for some academic reading. For a less academic take, you can read Gizmodo’s interview with Sander Otte, one of the paper’s authors.
 The drive features cholorine atoms on a copper surface, which results  in a perfectly square grid. A “hole” appears in the grid any time an  atom is missing, meaning you can remove atoms to create the on/off  dualism that’s essential to all data storage. “The combination of chlorine atoms and supporting copper crystal  surface that we found now, combined with the fact that we manipulate  ‘holes’ — just as in a sliding puzzle — makes for a much more reliable,  reproducible, and scalable manipulation technique that can easily be  automated,” said Otte. “It is as if we have invented the atomic scale  printing press.” Using this as the basis, the team managed to write all sorts of data,  including the entire text of Richard Feynman’s famous lecture, “There’s  Plenty of Room at the Bottom,” and Darwin’s “On the Origin of Species.”
