5D data storage and the future of optical technology

data 5dThe lifetime of 5D memory is 10^20 years at room temperature, indicating unprecedented stability among all techniques. Besides the benefits of multiplexing, 5D optical data based on nanogratings can be also erased5D 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
