Newest Developments for Data Storage

Encoding polarized light into durable quartz nanostructured glass, researchers at Southampton University successfully wrote and then read a file in “5D.” 3 spacial dimensions, polarization, and intensity. The storage capacity would be around 360 TB per disc. The read speed is 8 times faster than conventional drives, but write times might be much slower. The disc would last indefinitely and is rewritable. This technology is being called the Superman memory crystal.

Another disc using plastic can store 1 PB of data with 9 nm resolution. This is accomplished by combining an inhibition beam with a writing beam that compete over a chemical reaction for polymerization. Additionally, this can be used as a 3d printer at the nanoscale and could have other uses.
