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."

You're right, the technology isn't new. But that's not what the article is about. Its about GE developing a holodisc that can store up to 500GB of data, which is more than any previous disc.

Its nice to see some innovation, but I think that for the average consumer, flash memory will be the cheaper and more practical format. You just can't stick a holodisc in your pocket or on a keychain. Well, you could, but it might not work at the end of the day.

No, the title said "GE Makes Holographic Optical Storage Breakthrough", which is wrong because there was no breakthrough here since we've had this level of technology for some time, InPhase Technologies even advertises 300gb, 800gb, and 1.6tb solutions at their webpage.

This IS a breakthrough. Ge said that this is based on current Blu-Ray technology, so that it can read, and likely write, our current formats as well. It should also be cheap.

The non working InPhase technology will be VERY expensive, assuming they ever get it working.

No, that isn't what it said, and this still isn't a breakthrough. The article did not say that this disc was based off of Blu-Ray technology, it only said that GE's disc is similar enough to CD, DVD, and Blu-Ray technology in that future optical drives meant for GE's holographic disc would be backwards compatible, just like DVDs are with CDs, and Blu-Ray with CDs and DVDs.

Assuming they ever get it working? InPhase has been shipping their products for years. Did you even read this article?

It's a DailyTech headline.

Nuff said.
