GE Shows Off 1TB DVD-Sized Disks at the Emerging Tech Conference

Holographic Disk

( -- At the September '09 Emerging Tech Conference in Boston, GE announced it has been developing a 1TB DVD size disk that can be read by a modified Blu-ray player.

The first products using this technology will be 1TB drives used for archival storage. GE expects this to reach the market in two to three years with another two or more year before it's available to consumers.

GE is anticipating that this technology can store an entire 3D move that would be impossible to store on current blu-ray . The holographic drives will have a 3ms access time and data transfer rates up to five times faster than a DVD.

Holographic storage involves holograms, images of data being stored in layers on a DVD size disk. The drives work by splitting a laser beam into a reference beam and a signal beam, which is encoded with data. By crossing the two beams an interference pattern is created which is then stored on the disk.

Older versions of holographic drives store pages of a million bits stacked ten thousand deep at hundreds of locations on a disk. GE researchers discovered by reducing the page size to a single bit, called micro holograms, they could store as much data per unit area but was much easier to read. It turns out that the upper data layers can be read by a standard Blu-ray player and by slightly increasing the tracking range of the Blu-ray read head all layers can be accessed.

GE is planning to license the technology to manufactures for construction of the drives and disk. Peter Lorraine, GE lab manager stated at the Emerging Tech Conference, that license announcements could be expected soon.

I don't even know what I need such a disk for! Still, it's kind of nice to know such a technology exists! It kind of reminds me of the "Forbidden Planet" technology; i mean technology is getting there! Maybe, I could have all of my James Burke video's on one disk!? Or, maybe, all the mechanical universe, or Universe: the Infinit Frontier could all be had on one disk!? I'm thinking maybe I should wait till then!?

GE has healthcare services and this is a good DVD to store the DICOM imges as back ups

Yes it would be great to back up the 1TB hard drive

I know what I need it for. Data Backup. If 1) they can let you use them to store ANY kind of data on, 2) they are affordable enough to match the price of blank DVDs, and 3) they are stable enough to store for long periods of time, then I'll become a silent partner in the darn company.

If so, sign me UP!

The key to all this is price! How much for the 'modified' Blu-ray writer, several hundred dollars in todays market. And the DVDs will cost in the $10's each. If you're lucky enough to be in Canada they tax the blank media that can be used to record illegal music, with 1T the tax would be enormous.

the only thing i can think of is , GOD quality VVVVVVVVVVVVHD movies and sounds , but with tht we would require the quality if televsion etc. systems too ,also probably a lot of movies on it ....i mean a LOT .

As long as the price for the media is anywhere near the cost of a DVD I would buy it. I'd even buy them if they were 3 to 4 times the cost of a blank DVD, just the time saved of only needing to backup a fraction of the disks needed now would be worth the extra premium cost.

everyone is talking data backup but you missed the commercial properties... studios are spending 50 million dollars to convert each movie to 3D. These remakes take up a lot of extra space so in the event of release a 3D Toy Story like the one that just hit theaters this week you need blu-ray to be a little bit bigger.

Granted the storage is awesome but seriously they created TB optical disks a long time ago. wiki HD DVD its pretty impressive.
