GE Global Research, the technology development arm of the General Electric Company, on Monday announced a major breakthrough in the development of next generation optical storage technology. GE researchers have successfully demonstrated a threshold micro-holographic storage material that can support 500GB of storage capacity in a standard DVD-size disc.

“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,” said Brian Lawrence, who leads GE’s Holographic Storage program.

GE’s micro-holographic discs will be able to be read and recorded on systems very similar to a typical Blu-ray or DVD player. Holographic storage is different from today’s optical storage formats like DVDs and Blu-ray discs. DVDs and Blu-ray discs store information only on the surface of the disc; holographic storage technology uses the entire volume of the disc material. Holograms, or three-dimensional patterns that represent bits of information, are written into the disc and can then be read out. Although GE’s holographic storage technology represents a breakthrough in capacity, the hardware and formats are so similar to current optical storage technology that the micro-holographic players will enable consumers to play back their CDs, DVDs and BDs.

The GE team successfully recorded micro-holographic marks approaching 1% reflectivity with a diameter of approximately one micron. When using standard DVD or Blu-ray disc optics, the scaled down marks will have sufficient reflectivity to enable over 500 GB of total capacity in a CD-size disc.

GE has been working on holographic storage technology for over six years. The demonstration of materials that can support 500GB of capacity represents a major milestone in making micro-holographic discs that ultimately can store more than one terabyte, or 1000GB of data. In addition to pushing the limits of storage capacity, GE researchers also have been very focused on making the technology easily adaptable to existing optical storage formats and manufacturing techniques.

“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,” said Bill Kernick, who leads GE’s Technology Ventures team.

GE initially will be focusing on the commercial archival industry followed by the consumer market for its micro-holographic storage technology.

To my knowledge, the Holographic Optical Storage has already been invented in 1999 by a Romanian Physicist, Eugen Pavel. The technologies are very similar : use the whole volume of the media to store the information, not just the surface. It's called the HYPER CD and , at the time it was 10mm think but now has been refined to a much more usable format .

As in EU , even the CONCEPTS are patentable and even the deffinitions given by the inventors are similar : "optic tridimensional multilevel memory" ~ "three-dimensional patterns that represent bits of information" ... how is GE going to sell it's invention ?

Here's the info :

The Hyper CD-ROM is a tridimensional multilayer optical memory, a glass disk with storing capacity of over 10,000 Gigabytes (GB), which can be manufactured by using commercial equipment, informs Dntb web site. More precisely, the user can store on a disk with a 120 mm diameter and 10 mm thick more than 1 PB (1,000,000 GB).

The creator of such an amazing development is a Romanian citizen - Dr. Eugen Pavel - who graduated Physics at the Bucharest University, in 1976, was then awarded with the Romanian Academy Prize, in 1991, and 'Who's Who in the World', Marquis, 1997, and has over 40 scientific works published and presented at dedicates conferences. But what is again remarkable is the fact that Dr. Pavel has over 62 patents and patent applications.

The Hyper CD-ROM is, according to the definition given by the inventor, an "optic tridimensional multilevel memory" so it can store data in over 10,000 different levels inside a glass disk 10 mm high and 120 mm in diameter. "The most attractive aspect is that the support for storage (i.e. fluorescent photosensitive glass) is a very stable in time medium (information can be read during all the life of the glass - estimated to at least 5,000 years)," further writes Dntb.

The Hyper CD-ROM was showcased in Brussels EUREKA "48th World Exhibition of Innovation and New Technology", November 1999, and received several prizes such as the "Prix International de l'Organisation Mondiale de la Presse Periodique", the "Grand Prize of the "Kent Premium Lights Annual Awards for Innovation", 2000, organized by the Romanian Design Foundation.

At the time being, the Hyper CD-ROM technology is patented in 21 countries, including USA, Canada, Japan, Israel, but also other 17 European states.


Capacity: 10TB with extension to 100TB
Average data-transfer rate: 3Mb/s
Dimensions of CD-ROM-Drive: 80x150x300mm
Dimensions of CD-ROM: 10x?m
Thermic resistance: up to 550 deg. Celsius
Very high fiability
Stability in time (estimated to at least 5,000 years)

Yes, that's right. This was like more than 9 years ago. I don't know if he sold his pattent to the General Electric or the G.E. stoled the ideea from him and made more advanced resources, the point is that G.E. asumming the discovery is bullshit.
