The next time you worry about your family photos, or some geeky drunk college-fest you took part in, you should really consider where you’re saving your memories, because in a few years you’ll have data storage meant to last. Really – millions of years from now.
Besides lasting that long, the new data storage method invented by scientists can also hold huge amounts of information, because of the nano-scale elements that constitute the material’s basic structure. The group of researchers describes the new storage technique as of placing a single iron crystal only a few billionths of a meter wide inside a hollow carbon nanotube. Just like diamonds, nanotubes are among the most stable structures in existence. Once inserted inside the carbon nanotubes, the iron nanocrystals act as data bits, physically sliding from one end of the tube to the other in response to an electric current and in the process registering either a “1″ or a “0″ in the binary language of computers. “Nothing could be easier, electronically speaking,” says physicist and co-author Alex Zettl of the University of California, Berkeley.
As time goes by, nanotechnology finds its place in our lives more and more, but there’s also a limit to that – it remains to be seen which. You can see a demo of how bits are “moving” in the video below:
