Microholography milks 500GB out of DVD-sized discs

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.

this thing have been "in the air" for about a decade. They will release this technology when the hdd have more than 10TB.

I wonder when we will switch from CD/DVD - sized disks! x)

We already are. Games our starting to put them on one dvd instead of 7 CD's.

I think Taiwan's miCard solves that one

why would you want a 500gb dvd? It will take forever to burn stuff on it.

am sure the speed for dvd burners will increase as well.

i dont see a problem with more space on DVDs

why and what files at 500gb would you burn at once?

and probably this discs will require you to buy compatible writers which will support the speed of the current writers in the market.

It's these holographic discs that are preventing me from buying a blu ray disc. I see no point in buying those at any time.
