So anyways, I was chatting with middy just now.
I can't believe that you guys don't know about this:

"[FONT=Arial,Helvetica,Geneva,Swiss,SunSans-Regular]Imagine having the ability to record seven hours of high-definition video onto a single disk at 160 Mbps. By storing data in 3D throughout the depth of the recording media, not just on the surface, Tapestry™ holographic technology breaks through the historical limitations of data storage."
Holographic Storage Devices.
Basically, an image is burned in three dimensional space on a recording medium by two lasers. Because of the extra space, there is more surface area to write data to, and thus more data can fit on a single disc. A normal CD/DVD/HDVD/BD disc can only record on one surface. (Two surfaces with DualLayer DVDs.. and Three surfaces with newer TripleLayer HDVDs in development, which can hold up to 51GB of data.)
Holographic Discs can hold data on a single-layer with multiple depths. Basically, instead of just an x and y surface area for data, there is also a 'z' coordinate. The 'images' burned into the discs are simply light or dark areas, which resemble 'static' from an old television set.
Here's how it stacks up with current technology:
CD- 750MB Max
DVD- 4.7GB Max
DVD (DL)- 8.5GB Max
HDVD- 17GB Max
HDVD (DL)- 34GB Max
HDVD (TL)- 51GB Max (Theoretical Maximum.)
BD- 25GB Max
BD (DL)- 50GB Max
HDD (Perpendicular Recording)- 750GB Max
[/FONT]Tapestry™- 1.6TB Max (1,600GB!)
Tapestry™(RW)- 800GB Max
Currently, the discs are 5.25' and write-once, read many discs.
This means that you can only burn a disc once, much like a CD-R or DVD-R.
InPhase Technologies is currently working on a rewritable disc that will be able to hold as much as 800GB. The discs themselves are designed for usage up to FIFTY years!
(A CD/DVD today is designed for a limited max life of 5 years.)
InPhase Technologies is currently leading the forefront in this cutting edge field.
When the drives and discs are available in the next few years, they will be very expensive. Designed primarily for government and archivists.. companies that need to be able to store ALOT of data.
The devices should hit the consumer market some time after then.
