Created the “nuclear disk”


A team from Delft University of technology have created a new storage device, which is able to store 500 terabytes of information per square inch. The capacity of the device is made 1 KB.

In the new “Winchester” every bit of data is encoded by displacement of one chlorine atom on a substrate of copper atoms in one of two positions. As a result of displacement of atoms within the matrix of the other chlorine atoms formed “hole”. If the chlorine atom is in the upper position (“hole” at the bottom), this means 1. If the atom down (“hole” at the top) – 0. Further information is coded by binary code.

To demonstrate the technology, the researchers recorded on a copper plate part of the lectures of physicist Richard Feynman, who in 1959 stated that if he had the opportunity to build individual atoms in a certain order, you could save one unit of information per atom.

The entire text has been coded on the square 96 x 126 nm. For the record, the researchers used a scanning tunneling microscope. The professionals combine the bits in blocks of 64 bits. Each block has a token of the same “holes”. It works like a miniature QR code that contains information about the location of the block on a copper plate and showing a bad block or not.
