GE announced Monday that it has developed a micro-holographic disc that can store 100 DVDs. “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,” said Brian Lawrence, head of GE’s Holographic Storage program, in a company press release. The discs use micro-holographic storage technology to multiply storage space. DVDs and Blu-ray only store information on a disk’s surface. Holograms, on the other hand, can be written into the disc, enabling information to be stored on a disc’s entire volume. Multiple images can be placed in the same area, read by light at different
While CDs and DVDs store information in a liner fashion, holographic information storage is parallel, resulting in faster data transfer rates.
Micro-holographic discs can hold up to 500 gigabytes of information. In comparison, Blu-ray holds 25-50 gigabytes, while a DVD holds five. GE believes that micro-holographic discs will one day be able to hold a terabyte – 1,000 gigabytes – of information.
“This could be the next generation of low-cost storage,” Richard Doherty, analyst at Envisioneering, said in a New York Times article.
“GE’s breakthrough is a huge step toward bringing our next generation holographic storage technology to the everyday consumer,”GE's Lawrence said.
“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” Lawrence said.
