Europe: Researchers Boost HD Disc Storage With Microholography

Researchers at the University of Berlin in Germany said they have devised a method of data storage that will grow storage capacity for HD DVD and Blu-Ray Disc (or a new disc format) to 500 GB, which is many times more than current HD discs.

The researchers, a partnership of the Universita Politecnica delle Marche in Italy and the Budapest University of Technology and Economics in Hungary, used a “microholographic” recording technique that interacts with nanostructures inside the disc to store data within it (rather than on a disc surface), according to

Dubbed the “Microholas Project,” HD and other content on a 500 GB disc can stored in up to 50 layers. Now a new goal for some researchers for storage is a cool 1 TB per disc.
