A new magnetic recording medium made up of tiny nanospheres has been devised by European researchers. The technology may lead to hard disks able to store more than a thousand billion bits of information in a square inch.

Just to put that in perspective, that’s over 113 terabytes per square inch. You know that little SIM card in your phone, or the flash card in your camera? That would hold 113+ terabytes all by itself.

The future is soon.
