angrykeyboarder writes "Scientists have discovered a way to fit 500 GB of data onto DVD-sized discs. These discs would be created with a process called 'microholography, which combines multilayer storage of data with holographic imagery. From the article: 'Microholography allows data to be stored in three dimensions. The technology works by replacing the two-dimensional pit-land structures currently found on CDs and DVDs with microgratings, which are holographically induced using two laser beams. In other words, instead of recording to a series of bumps and pits like standard CDs, the new technology creates three-dimensional holographic grids that can be used for reading and writing data throughout the physical structure of the disc.'"
