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 360 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 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.[3]
