5D optical data storage (also branded as Superman memory crystal,

terabytes worth of data[3][4] for billions of years.[5][6][7][8] The concept was experimentally demonstrated in 2013.[9][10][11] Hitachi and Microsoft have researched glass-based optical storage techniques, the latter under the name Project Silica.[12][13]

The "5-dimensional" descriptor is for marketing purposes, since the device has 3 physical dimensions and no exotic higher dimensional properties. The fractal/holographic nature of its data storage is also purely 3-dimensional. The size, orientation and three-dimensional position of the nanostructures make up the claimed five dimensions.[3]

Technical design

The concept is to store data optically in non-

gold or silver nanoparticles embedded in the material, their plasmonic properties can be exploited.[1]

According to the University of Southampton:

The 5-dimensional discs [have] tiny patterns printed on 3 layers within the discs. Depending on the angle they are viewed from, these patterns can look completely different. This may sound like science fiction, but it's basically a really fancy optical illusion. In this case, the 5 dimensions inside of the discs are the size and orientation in relation to the 3-dimensional position of the nanostructures. The concept of being 5-dimensional means that one disc has several different images depending on the angle that one views it from, and the magnification of the microscope used to view it. Basically, each disc has multiple layers of micro and macro level images.[16]

Recorded data can be read with a combination of an optical microscope and a polarizer.[17]

The technique was first demonstrated in 2010 by Kazuyuki Hirao's laboratory at the Kyoto University,[18] and developed further by Peter Kazansky's research group at the Optoelectronics Research Centre, University of Southampton.[19][20][21][22] Discs recorded from that time have been tested for 3100 hours at 100°C and shown to still work "perfectly" ten years later.[23]

Uses

In 2018, Professor Peter Kazansky used the technology to store a copy of Isaac Asimov's Foundation trilogy, which was launched into space aboard Elon Musk's Tesla Roadster in association with the Arch Mission Foundation.[24]
