A few years ago, holographic media almost seemed taboo, but this year at CES 2006, InPhase is demonstrating compact holographic storage systems

A few years ago, IBM researchers were already building prototypes for the development of storing data using holograms. IBM’s Almaden Research Center built a precision system called Photorefractive Information Storage Materials (PRISM) to test and evaluate photosensitive materials.

At its basic, a blue-green argon laser similar to the one above is split into a reference and an object beam. The object beam, which is the carrier for the data is expanded to fully illuminate a spatial light modulator (SLM). An SLM is basically a LCD panel that displays a page of binary data represented by a grid of pixels being either on or off. An interference beam results from the laser passing through the SLM and is recorded on the media (originally photosensitive crystal).

Systems like the ones IBM worked with were enormous in size and required a great deal of power to operate. Today however, InPhase brings this technology down to the size of an average external storage drive with the media being no larger than a DVD-RAM cartridge.

InPhase is calling its media technology Tapestry and is currently developing and sampling three variants: Tapestry HDS3000 uses green laser to read and write while Tapestry HDS4000 uses red and Tapestry HDS5000 uses blue. The different wavelengths of the lasers allow for different storage capacities and InPhase has already been shipping out media to manufacturers for evaluation since Q4 of 2005. Development and production is going well says InPhase:

InPhase will be the first company to deliver a holographic product for professional archive applications, in late 2006. The media for this product will be offered through its strategic partner, Hitachi Maxell Ltd.

Currently however, InPhase is only sampling a read only version of its discs called H-ROM media (Holographic-ROM).

The company says that initially, H-ROM discs will be able to hold 300GB of data on a 130mm disc and transfer at a rate of 20MB per second. The media will use the red laser because of pricing and availability until green and blue emitters come down in price.

yay, skip blu-ray, skip hd-dvd, crappy formats, wait a few years for this. dvd dl will do until then.

Sampling already? I thought this stuff was in completely experimental stage.

Perhaps it really could leap-frog all the cruft. But I bet the movie companies won't allow it to live unless it's stuffed with DRM.

Incidentally, it'd be interesting to see how fast this work even in the prototypes.

at 20MB per sec, its going to take an awful long time to write one.

I agree. This B-Ray and HD-DVD issues are making me sick. Let's just skip them altogether.

I dont need these h-rom to store movie, so DRM is not an issue. I just need them to hold my family video and pictures, which are currently takes 10+ dvds(some of them DL) to store.

You wont need 300 GB to store yours videos even in HDV...

Just think, if you had your familys vedeos on tape they wold look 1000% worse and ocupy 1000% more space.

Stop crying!
