General Electric unveiled 500Gb storage Capacity Micro Holographic Disc (MHD) aimed at the Archive industry. The Technology is still in laboratory stage and not available to the consumer market. The disc can store data similar to 100 DVDs and is thought to be the next big technology shelving the archive market. The disc is similar in size to a DVD but the mechanism of storing data is totally different.
Brian Lawrence, who leads GE’s Holographic Storage said on the GE Research blog: ‘Very recently, the team at GE has made dramatic improvements in the materials enabling significant increases in the amount of light that can be reflected by the holograms’
COMPARISON WITH OTHER STORAGE DISC:
DVD can store upto 4.8GB.
Blue-Ray Disc can store upto 25GB-50GB.
Micro-Holographic Disc can store upto 500GB.
TECHNOLOGY USED:
Micro-holographic Discs can store more data than the DVDs and Blu-Rays because they can store information on the disc in three dimension, rather than just pits on the surface of the Disc. While the technology is still in the laboratory stage, GE believes it will take off because players can be built which are backwards compatible with existing DVD and Blue-ray technologies.
Micro-Holographic technology has been at the centre of attention and in the news for quiet a number of years for researchers as these discs are seen as reliable and consumer friendly form of storage option. General Electric at this point in time has to work with hardware developers to give this technology a proper hardware resource. Its still ahead of its time, since the Blue Rays have yet to fully flood the consumer market.
Technama would be bringing more on this technology as new updates are available.
