GE tries to refocus image of holographic storage

Holographic storage involves holograms, images of data, being stored in layers in a CD-sized disk's recording surface. The images are created by two laser beams and read by a laser beam. GE's researchers at its Applied Optics Laboratory managed to shrink these images, calling them micro-holograms. They achieved this to the point where the images were also reflective enough - 200 times more so than before - to be read by optics that could be used to read existing optical formats. A CD-size disk could store 500GB using this technology, with 1TB and greater capacity potentially possible in the 2011/2012 period.

This compares to InPhase's 300GB capacity, although InPhase has predicted a ramp up through 800GB to a 1.6TB capacity point and a 120MB/sec transfer rate. This was said to be appearing in 2010, but that was in 2007, so we'd better assume a 2012/2013 date if InPhase holds to its course. There is a deal of overlap here between GE and Inphase capacities and capacity roadmaps.
