500Gb Holographic Storage Demoed
 

GE researchers have demonstrated a new micro-holographic storage material that can support 500GB of storage capacity in a standard DVD-size disc - equal to the capacity of 20 single-layer Blu-ray discs, or 100 DVDs.

GE says the discs can be able to be read and recorded on systems 'very similar' to a typical Blu-ray or DVD player and that, unlike DVDs and Blu-ray discs, which store information on the surface of the disc, holographic storage technology uses the entire thickness of the disc material.
