Diamond data storage breakthrough writes and rewrites down to single atom

Diamond is a promising material for data storage, and now scientists have demonstrated a new way to cram even more data onto it, down to a single atom. The technique bypasses a physical limit by writing data to the same spots in different-colored light.

Diamond has great potential as a data storage medium – recent developments have produced 2-inch (5-cm) wafers of the stuff that can store the equivalent of a billion Blu-Ray discs. Intriguingly, it works not by writing data to the diamond itself but to tiny nitrogen defects in the material. These defects can absorb light, earning them the name “color centers.”

Usually, optical memory technologies have a hard limit to how fine they can write data – after all, there’s a minimum diameter that a laser beam can be focused to. Known as the diffraction limit, this scales with the wavelength of light used.

No just on the atoms of a diamond, but each light frequency can store a bit of information on the same atom.

I wonder if lab created diamonds will work the same as real.

Interesting. Invest in glass, because glass is the future.
At least we know why we have so much sand in the world.

20 years ago Neal Stephenson wrote The Diamond Age. Stone Age, Bronze Age, Iron Age...Diamond Age. Good stuff.

Cool, they can store data on a random carbon atom. Or a nitrogen one in the diamond...?

Can they store it in more than just one?

How do they keep track of location of each bit? Can the system reliably reod/write to the atom it’s supposed to, and not the one a couple microns over?

Yes. That’s the whole point.

Another unique aspect of this approach is that it’s reversible. “One can write, erase, and rewrite an infinite number of times,” Monge noted. “While there are some other optical storage technologies also able to do this, this is not the typical case, especially when it comes to high spatial resolution. A Blu-ray disc is again a good reference example -- you can write a movie in it but you cannot erase it and write another one.”
