New development in Holographic storage 500GB disc
Holographic disc technology is capable of dwarfing traditional optical media due to its density. The discs make use of microscopic holograms encoded with light information, which are then accessed by a laser.
While several tech companies have been developing holographic discs for years, GE's successful demonstration is significant because its technology uses smaller, less complex holograms
GE expects its holographic disc could make it to mass production in 2011 or 2012, and cost less than 10 cents per gigabyte.
