Holographic Storage For The Masses
jmoo writes: "Ars Technica has an article on startup company looking to produce holographic storage for commercial sale. The company, InPhase, supposedly is backed by Lucent and is predicting storage densities of 300 gigabits per square inch." "Backed by Lucent" certainly sounds a lot less sketchy than the repeated but never confirmed claims of extremely dense storage using multi-layer CD-ROMs.
Here's a direct link to the actual article.
At a repletech conference three years ago,I saw a guy from Lucent give a talk about this. At that point, they had built a system from off the shelf components that worked. They had acheived something like 40gb on a 5.25" platter. He was predicting that they would be to market in three or four years with a 150 gb system. His goal was 250gb plus on a 5.25" disk.
This was a real system. Based on the talk, my company at the time initiated some discussions with Lucent. My company was a Japanese giant that was into many kinds of data storage media. They took it seriously.

I supply (again) the links to the Lucent site, complete with the original press release of 30 Jan 2000 with all the links including the movies, and everything else
Next time I'll remember to use smaller words in the submission.
sometimes people don't get it even if you supply pictures.

A standard CD has 15.315 square inches of active area on its surface.
At 300gb/sq.in. a standard CD could hold 575.3gb. Thus it would only take two disks to finally get to my magical holy grail of owning my own

I remember seeing an article on IBM's R&D site a few years about developing holographic storage. I never really heard much after that... This is what I managed to dig up on their current site... it's a nice little overview: http://www.can.ibm.com/he/multiversity/Sum98/holog raph.html

Great, now when I find myself searchig for more spaces for my mp3/pron collection, I can just cook up a batch of jello. I can probably get a greater bit density by using different colors from the different flavors.
Would I be able to store more info in blue-rasberry as opposed to cherry due to the wavelength difference?
I guess this brings a new meaning to home-brewed system.
Yep, I never spell check.

For all intensive purposes, "whom" is no longer a word. That begs the question, "who cares"?
storage does not merely mean layered storage, as in the scotch tape and multi layer DVD examples.
In holographic storage a photosensitive medium is exposed to the interference pattern that is generated when an object laser beam, with the data encoded in it, is intersected by a second, coherent laser beam. The photosensitive medium will then replicate these interference fringes as a change in optical absorption. Data is retrieved from the medium by exposing it to light from one laser beam.
In the scotch tape laser burning and multi layer DVD examples, the laser merely burns holes on a 2D surface in many stacked surfaces. To read back you just focus the diode lasers' objective lens on whichever surface you want to read. This is considered inferior to the data densities possible with holography.
