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.More info at The Register.
