Diamonds are your data’s best friend
 

Another storage option

A team of boffins have come up with a new way of saving huge amounts of data on diamonds.

City University of New York Professor Carlos Meriles and his colleagues took advance of a defect in diamond which occurs when a carbon atom is replaced by a nitrogen atom in the diamond's lattice structure. Nitrogen vacancy centres trap electrons, but the electron can also be forced out of the defect by a laser pulse.

So, the team used optical microscopy to read, write and reset information in a diamond crystal.
