GE's 500GB holographic storage discs. Yup, holograms!~

GE has developed a micro-holographic disc that's the same size as present-day CD, DVD and Blu-ray discs. Instead of the two-dimensional surfaces used for Blu-ray's 50GB, holographic storage uses three dimensions to store digital data. These discs can store 500GB of data by using holographic light patterns to densely pack three-dimensional data~

While still in the developmental phase at this point, industry experts are hopeful that it could become the next form of low-cost storage for consumers. Best news out of this development is that new micro-holographic players will be backwards compatible to play CD, DVD and blu-ray discs~
