"Superman memory crystal" could store hundreds of terabytes indefinitely
Recently, there have been advances in the area of digital data storage promising outstanding data density and super-long-term data storage. A new data storage technology developed at the University of Southampton can do both. Due to its similarities to the “memory crystals” used in the Superman films, it has been dubbed the "Superman memory crystal."
Researchers at the University of Southampton have created an extremely dense and durable memory that can store 360 TB of data on a single disc for an indefinite amount of time. The structure, which is made of glass, can resist temperatures up to 1,000° C (1,800° F) and would be perfect for creating portable data archives that can truly stand the test of time.
Information is written using a femtosecond laser, which fires extremely short (a femtosecond is a millionth of a billionth of a second) and powerful bursts of light inside a dense three-dimensional nanostructured glass.
