GE has announced a breakthrough in holographic storage, which the company believes will bring it much closer to the day when it can store up to 500GB on a single optical disc. Like other efforts, GE has been working for some time on an optical storage medium that uses holograms to store data in three dimensions; this is in contrast to conventional optical discs, which use layers of pitted metal to encode 2D data patterns that can be read by bouncing a laser off of them.
