General Electric shows off optical disc storage breakthrough – 500GB disc

Researchers at General Electric (G.E.) have announced a breakthrough in optical disc storage – 500GB on a single disc (the equivalent of about 100 DVDs using standard technology; Blu-ray discs can hold much more).  G.E. uses holographic storage techniques to achieve this capacity.

Despite the discovery, there is no telling if this will take off commercially at this point. It will be a matter of economics as to whether the technology can be brought to market at a price that consumers will be willing to pay.
