Several companies, including Hitachi/Maxwell and Optware, are working on holographic media. In the latter's case, projected disc space - on something the size of a DVD - will be in the multiple terabyte range (100 times more than HD DVD or Blue-ray). Optware's HVD format works by sending two lasers, one red and one green or blue, toward the disc. A layer reflects the green or blue laser and lets the red laser pass through. The red laser reads a layer of pits and lands (like with a regular DVD). The green or blue laser reads the data containing layer in three dimensions (back and forth, as with a DVD, and also vertically). That's thousands of 1080p/24 content on one single disc. Don't expect it in a home format any time soon though.

P.S. Makes me think about the famous quote by Bill Gates in 1981: "No user will ever need more than 640 kilobytes of RAM". Classic!

It was enough to put a man on the moon, It's enough for me.
