Holographic Disc Breakthrough

Scientists at GE’s Global Research Center in upstate New York announced a breakthrough in the pursuit of holographic data storage. They have successfully demonstrated technology that can put 500 gigabytes onto a single DVD-sized disc. The process works by imprinting chemical changes in the form of patterns (holograms) within the disc. Those holograms are then read by lasers, similar to the ones in Blu-ray players. At 500GB, these holographic discs could offer 20 times the capacity of a single-layer Blu-ray disc.
