Holograms !!

Holographic memory offers the possibility of storing 1 terabyte (TB) of data in a sugar-cube-sized crystal. A terabyte of data equals 1,000 gigabytes, 1 million megabytes or 1 trillion bytes. Data from more than 1,000 CDs could fit on a holographic memory system. Most computer hard drives only hold 10 to 40 GB of data, a small fraction of what a holographic memory system might hold...
CD's are gonna fade out in the coming few decades...
Holograms are the next generation data storage devices..
Hologram stores the data in the form of pictures (For the physics part of it.. It stores both wavelenght and path diffence of the wave hece enabling 3D viewing.)
Its major advantages are its high data storage capabilites and that the entire data can be retrieved even by getting a very small piece of hologram, but only a very small reduction in image resolution.

With such technologies on the market, you will be able to purchase the first holographic memory players by the time "Star Wars: Episode II" is released on home 3-D discs. This DVD-like disc would have a capacity 27 times greater than the 4.7-GB DVDs available today, and the playing device would have data rates 25 times faster than today's fastest DVD players
