5D Optical Storage Allows Storing 500 TB Data On CD-Sized Disc

New 5D storage mechanism now allows storing 500TB of data on a CD-sized glass disc. Researchers used near-field enhancement which allows creation of nanostructures using weak light pulses to store information in glass at faster speed.

Researchers wrote 5GB of data on the disc; but confirmed that it can store about 500 TB of data; making the disc 10000x denser than blu-ray disc.
