Holographic storage?

Even since astronaut Dave Bowman disconnected the HAL 9000’s holographic memory in 2001: A Space Odyssey techies have been wondering when we could buy real holographic storage. Now we know: May, 2008.

Promising super-high density and excellent media flaw resistance, holographic storage has been an ever-receeding technology for years. You can buy nifty 3D skull and crossbones holograms – technically a form of storage – but no one had figured out how to turn a lab project into a product. Until now.

How does it work?
Holograms use 2 coherent laser beams – a reference beam and an illumination beam – to create an interference pattern that is recorded on photo sensitive media. Shine a laser on the recorded interference pattern and the original image is reconstructed in glorious 3D. As the laser moves around – or you do – you see the image from different perspectives.
