5-D Recording

Let me start this by saying I'm a pretty bright guy. I can be fooled as well as anyone - maybe even better than some (or even most) - but I generally catch-on pretty quickly. So I am going to present this to you as best I can, but link to the article itself for further reading, as I can't make much of it! For whatever reason, I always have this problem with BBC articles on science and technology; maybe they really are that far ahead of us, educationally, but I have a sneaking suspicion they get reporters with degrees in these fields to write for them. Either that or they just regurgitate a lot of stuff from the original papers.

Anywho, a team of researchers have discovered a way to use both color wavelengths and polarization to vastly expand the amount of space available on a disc. Where some of this had been posited before, this team took it to the next level; combining both techniques allowed them to "achieve unprecedented data density." Currently, information is recorded on only one color wavelength. The team incorporated gold particles into their medium and used several layers of glass as the media.

That's... I mean, that's pretty much it. The guys said, using their methodology, the limits could be pushed far beyond the theoretical 1.6 terabytes (300x the amount you can get on a single CD today) they achieved in their experiment.

The rest is basically Greek to me.
