GE holographic disc stores 500GB of data

Researchers at GE have validated technology that will one day usher in the next generation of optical storage -- holographic storage. The researchers have developed a disc the size of a standard DVD that can hold 500GB of data. The researchers say that conventional optical storage discs only store information on the surface of a disc while holographic storage can store information on the entire volume of the disc material.

Tiny holographic bits of information are written to the disc in patterns and can then be read back by the drive. The capacity of holographic discs are a breakthrough, but the technology used in the process is similar enough to the current DVD and Blu-ray technology in wide use that future optical drives will be able to read CD, DVD, Blu-ray, and holographic discs.

GE's Brian Lawrence said in a statement, "GE’s breakthrough is a huge step toward bringing our next generation holographic storage technology to the everyday consumer. Because GE’s micro-holographic discs could essentially be read and played using similar optics to those found in standard Blu-ray players, our technology will pave the way for cost-effective, robust and reliable holographic drives that could be in every home. The day when you can store your entire high definition movie collection on one disc and support high resolution formats like 3-D television is closer than you think."

GE reports that its researchers have been able to successfully record micro-holographic marks approaching one percent reflectivity at a diameter of about one micron. The one-micron size will allow a disc the size of a conventional DVD to hold 500GB of data. GE has been working on holographic storage for six years and the 500GB capacity is a milestone in its research. The researchers hope to eventually devise a way to store 1,000GB of data on a single disc using the holographic process. In 2007, InPhase started shipping holographic writers and media that could store 300GB per disc.

GE's Bill Kernick said, "GE’s holographic storage program has turned the corner, and with this milestone we can now intensify our efforts in commercialization opportunities. We’ll continue to engage with a variety of strategic partners to create the best route from product development to introduction into the marketplace."

RE: holo/optic/disc storage is dead

You're assuming these would somehow make it into DOD machines in the next decade. Considering government contracts go to the lowest bidder the DOD machine I have right now is still using a DVD/CDRW drive. Specialized applications may get them but only because they would need that capacity to move data outside the DOD network. Which is not very common.

The big problem with the flash media ban is that most of the stuff I want to move is small, and burning a CDR for a file that would fit on a floppy disk (which we don't have any more) seems a waste.

Again, Windows 7 may fix the problem but it will be years before the DOD transitions to it I'd imagine. We just in the last year converted to XP.

Windows 7. Hell, we haven't really even started moving to Vista.
