Holograpic Discs

[Anonymous]

I was wondering if anyone had heard of the new format 'Holographic discs'. I watched a program a year or two ago about a German company who were allegedly in the testing phase of a new format. These discs were transparent orange, and the developers claimed they could hold up to 250 times the data on a DVD disc. They claimed that instead of using layers, the information would be stored on small suspended particles embedded in the disc and the optical reader would move about the disc, reading information from a finite number of angles. Thus giving a huge storage capacity.

I have failed to see any of this materialise and was wondering if anyone out there had heard or seen anything to suggest they will arrive or have been shelved.

Thanx

recently i came upon articles from bell labs and IBM wherein they described the working of the holographic storage technique,i think in due time we will be moving into the holographic genera.

Cost and Support are two major disadvantages to this median.

100GB CD-sized prototype drives are available right now, with professional and consumer versions promised within a few years that are backwards-compatible with CDs and DVDs. For more info. on how Blu-ray and holographic data storage can seamlessly fit together at 100GB, 1TB and beyond, see the holographic data storage posting at:

...and what about 50GB or more on a minidisc-sizd disc? What could you do with that?

Inphase Technologies has begun shipping the first blue laser holographic media, the Tapestry HDS5000. In comparison to current green laser-based products, the shorter wavelength of blue lasers will allow even higher capacities. The first generation blue-laser products will commence with a conservative 135GB on a CD-sized disc, using fairly simple recording techniques, and will be limited to 10-20MBps (80-160Mbps) data-rates, but the current read/write technology can potentially support data transfer rates of 100MBps or more (800Mbps). This will be the first commercial exploitation of the wave properties of light from a blue laser diode.

That would hold a lot of songs for an MP3 walkman. :P

But in all reality it would be great for deep wilderness hiking. Huge resolution satellite images of the area (LARGE area) not to mention the possibility of having high quality video of weather fronts your GPS can DL as you sleep. Play it on one of those upcoming flexible screens like you see in the movie Red Planet or whatever.

I love dreaming.

PS: I was just looking around the forum and found out I stole someones name. Oops.

Sounds like a great idea, JustYou!

Those flexible screens are closer than you think. Based upon organic light-emitting diodes [OLEDs], the active materials can be printed on to a thin plastic sheet - and rolled up if so designed. OLEDs have hit the mobile phones market, because they can use much less power than an LCD display - one manufacturer already has one (the outer of two screens) which is always on, and shows the time and other useful info. Whilst large screen versions aren't yet ready to replace LCDs , many manufacturers see them as the next display technology after LCDs. Where LCDs have a backlight and are typically over an inch thick, large screen OLEDs can potentially be a few millimetres thick or less - for permanent installations you might even be able to "wallpaper" them on to your wall! 8)
