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."

There's also the "its mine" factor.

A digital download I can't touch. A movie on a disc or flash card I can. I prefer physically having something to not.

Yup I heard about halogram optical storage breakthroughs 4-5 years ago yet the tech is still not available on any consumer grade level.

If there is one thing I have learned from SED/OLED is dont get excited over news about breakthroughs and even if it could be available there are attorneys and patent disputes which will further delay innovation.

I agree 100% on the not getting excited for the scientific breakthroughs. Like you said new ideas and concepts usually take a decade or so to become products. By then the demand might be gone or something else could beat them to it.

But I think what you would have heard about 4-5 years ago was the scientific breakthorough of discovering halographic storage or perhaps a proof of concept. This article however implies that they are far beyond that, that they have a functional disc. If their claims that it uses technology that is similar to current optical drives then this might not be more than a few years away from consumer use.

Not sure what he read, but what I read about 4-5 years ago was a prototype, not some theoretical process. It did read at a slower than a snail crawling in molasses rate of 3 kb/s on a disc that stored more than even top of the line Blu-Rays discs we can purchase today. It was not yet practical by any means.

I second that to an extent. Not because I really need to caress my game discs.

Steam and others have made huge improvements. It's easy to pull down all the games I use after a format, but the day Steam some how dies, if I can't get copies of those games, I'm coming after someone.

That is why I ran out to get a physical copy of Empire Total War. Not because Best Buy grants me the USS Constitution (though that is a bonus).
