Microholography: 500GB DVD-sized discs

Jul 10

A group of scientists working together with the Institute of Optics and Optical Technologies at the Technical University of Berlin claim to have discovered a way to store 500GB worth of data on DVD-sized discs. The scientists are members of the Microholas Project, coordinated by Dr. Susanna Orlic, which plans to double the storage capacity to 1TB by 2010.

The Project aims to implement a microholographic recording techniques which record data to nanostructures in the recording process. By combining multilayer storage and holographic multiplexing, “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.

  7. The very first show of the new series, broadcast on Saturday, featured a kissogram, a naked Physician and a “sexed up” Tardis.During the unique 65-minute episode, The Eleventh Hour, in which Physician Who had 20 minutes to save Earth from aliens identified as the Atraxi, his new companion, Amy Pond, was revealed as a kissogram dressed in a skimpy policeman’s outfit, complete with mini-skirt and handcuffs. In one scene, Amy, played by the actress Karen Gillan, told the Doctor that her kissogram repertoire also included nuns and nurses’ outfits. Discover out more at Sci Fi Fan.
