Holografisk lagringsteknik har det talats om under många och tekniken fick en hel del fokus i samband med att de optiska lagringsformaten Blu-ray och HD DVD dök upp. Hittills har den utveckling som skett på marknaden för holografisk lagring varit riktad mot industrin och företagsmarknaden men nu sägs formatet nått ett genombrott genom utveckling från företaget General Electric. Forskare på företaget har visat upp holografiska lagringsskivor som med samma i fysiska format som en DVD-skiva kan lagra hela 500GB data. Som även ska kunna läsas och skrivas i liknande enheter som används för dagens optiska format. Vilket bör göra formatet betydligt mindre kostsamt än de holografiska lagringslösningar vi hittills hört talas om.

GE Breakthrough Validates Technology to Enable 500-Gigabyte Disc
GE’s Micro-Holographic Discs will have 20 times the storage capacity of a standard Blu-ray disc and be read with systems similar to todays Blu-ray and DVD Players
NISKAYUNA, N.Y.–GE Global Research, the technology development arm of the General Electric Company (NYSE: GE), today 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 500 gigabytes of storage capacity in a standard DVD-size disc. This is equal to the capacity of 20 single-layer Blu-ray discs, 100 DVDs or the hard drive for a large desktop computer.

GEs 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 todays 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 GEs 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 one percent 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.
GEs breakthrough is a huge step toward bringing our next generation holographic storage technology to the everyday consumer, said Brian Lawrence, who leads GEs Holographic Storage program. Because GEs 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 has been working on holographic storage technology for over six years. The demonstration of materials that can support 500 gigabytes of capacity represents a major milestone in making micro-holographic discs that ultimately can store more than one terabyte, or 1,000 gigabytes 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.
GEs holographic storage program has turned the corner, and with this milestone we can now intensify our efforts in commercialization opportunities, said Bill Kernick, who leads GEs Technology Ventures team. Well continue to engage with a variety of strategic partners to create the best route from product development to introduction into the marketplace.
GE initially will be focusing on the commercial archival industry followed by the consumer market for its micro-holographic storage technology.
