GE's new disc can hold 100 DVDs.

From NY Times:

General Electric says it has achieved a breakthrough in digital storage technology that will allow standard-size discs to hold the equivalent of 100 DVDs.

The storage advance, which G.E. is announcing on Monday, is just a laboratory success at this stage. The new technology must be made to work in products that can be mass-produced at affordable prices.

But optical storage experts and industry analysts who were told of the development said it held the promise of being a big step forward in digital storage with a wide range of potential uses in commercial, scientific and consumer markets.

“This could be the next generation of low-cost storage,” said Richard Doherty, an analyst at Envisioneering, a technology research firm.

The promising work by the G.E. researchers is in the field of holographic storage. Holography is an optical process that stores not only three-dimensional images like the ones placed on many credit cards for security purposes, but the 1’s and 0’s of digital data as well.
