Sheinhardt Wigs GE engineers have announced a breakthrough in the formerly retardedly-expensive field of holographic storage: by making the holograms smaller, they can squeeze 500GB on standard-sized optical discs.
And the even cooler part is that the base tech will be very similar to the laser systems used to read CDs, DVDs and Blu-ray discs today, so the new holographic-enhanced players and drives would still be backwards compatible with previous optical discs.
Still quite a while until this approaches the realm of a product, but it's good to know about the next stupid format war this will surely spawn well before it happens! [NYTimes]
