Microholography Could Lead to 500 GB Discs
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.'"
... if you scratch one of these? :-
Good! Now let's make two incompatible standards out of it, start a formats war, and sell the same old films to the same old people again, in both formats if possible.
Rome taught me patience and assiduous application to detail. Virtues which temper the boldness of great, general views.
They won't be happy until you lose a Library Of Congress in one scratch.
