GE Develops Disc Capable of Storing 100 DVDs

28 Apr, 2009 By: Erik Gruenwedel

General Electric Co. said its researchers have developed next-generation optical-disc technology that can accommodate content from 100 standard DVDs on one disc.

GE Global Research, which has been working on holographic technology for six years, successfully demonstrated a threshold micro-holographic storage material that can support 500GB of storage capacity in a standard-DVD-size disc.

This is equal to the capacity of 20 single-layer Blu-ray Discs, 100 standard DVDs or the hard drive for a large desktop computer. It could also accommodate multiple 3-D movies.

GE, which owns NBC Universal, including Universal Studios Home Entertainment, expects initial adopters to be commercial entities looking to transfer bulk data from magnetic-tape archives. In the future, the disc could be marketed to consumers seeking to store movies, videos, photos and related digital media.

The company said it hopes the micro-holographic discs ultimately could store more than one terabyte, or 1,000GB of data. In addition to pushing the limits of storage capacity, GE researchers have been focused on making the technology easily adaptable to existing optical storage formats and manufacturing techniques.

“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,” said Brian Lawrence, who leads GE’s holographic storage program. “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.”
