Microholography milks 500GB out of DVD-sized discs

post #1 of 15
Thread Starter 
Quote:
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...

No. It still has to find distribution. They've been doing this for a while now.

I think they use a different type of laser than Blu-Ray,
and hopefully they'll consider this as a viable movie medium
in the future. (Taking a stance against unfair DRM's, and
relying in the sheer size of movie files (PS3 Approach)).

Mmmmm... Uncompressed 1080p goodness (even then I don't
think 500GB is enough).

500gb is more than enough for an uncompressed 1080p Feature-Length film.

That's like two or three.

And seeing as how it wouldn't be uncompressed anyway (no benefit with today's compression methods), it's like 8.

the type of laser doesnt really matter (it does look like a blue laser though) -- what matters is the fact that theyre using holography to store data 3 dimensionally instead of 2D like ordinary discs.
Quote:
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.

not long ago they said that in theory the capacity will reach 3.7 TB's.....they seem to be on the way there

^capacity of what? there are still many forms of storage technology on the horizon, and ones i'm sure we've never even imagined

still cool, though. 500GB!

The lazer does matter the smaller the better and the finer the piont it can focus on the dvd,ture they are using 3d tech but the lazer still matter,the only real difference between blu ray and a dvd is the lazer that it uses to read and right the into in to the disc
