5D optical data storage explained

5D optical data storage (also branded as Superman memory crystal,[1] a reference to the Kryptonian memory crystals from the Superman franchise) is an experimental nanostructured glass for permanently recording digital data using a femtosecond laser writing process.[2] Discs using this technology could be capable of storing up to 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 only a marketing term, 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 comprise the so-called five dimensions.

Technical design

The concept is to store data optically in non-photosensitive transparent materials such as fused quartz, which has high chemical stability. Recording data using a femtosecond-laser was first proposed and demonstrated in 1996.[1] [14] [15] The storage medium consists of fused quartz, where the spatial dimensions, intensity, polarization, and wavelength are used to modulate data. By introducing gold or silver nanoparticles embedded in the material, their plasmonic properties can be exploited.[1]

According to the University of Southampton:

Recorded data can be read with a combination of an optical microscope and a polarizer.[16]

The technique was first demonstrated in 2010 by Kazuyuki Hirao's laboratory at the Kyoto University,[17] and developed further by Peter Kazansky's research group at the Optoelectronics Research Centre, University of Southampton.[18] [19] [20] [21] Discs recorded from that time have been tested for 3100 hours at 100°C and shown to still work "perfectly" ten years later.[22]

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.[23]
