GE Claims Holographic Media Breakthrough Capable of 500GB Discs

Hold the boat, Blu-ray, a breakthrough in optical storage technology could prove to be game changing, according to General Electric. GE today announced that its researchers have successfully demonstrated a threshold microholographic storage material they say can support 500GB of storage capacity in a standard DVD-sized disc. That breaks down to about 20 times the storage capacity of a standard Blu-ray disc and is equivalent to 100 regular DVDs, the company says.

"GE’s breakthrough is a huge step toward bringing our next generation holographic storage technology to the everyday consumer," said Brian Lawrence , who leads GE’s Holographic Storage program. "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."

GE's holographic storage technology makes use of the entire volume of the disc material rather than just the surface. Three-dimensional patterns represent bits of information, a process GE has been working on for over six years but has only just now turned a corner with the latest breakthrough.
