GE’s Research team has announced advancement in technology that elevates the development of optical storage technology. With a demonstration, they have shown that a threshold micro-holographic storage material can hold 500 GB storage capacity within a standard DVD disc. Sounds interesting, doesn’t it? Putting aside all those bulky (which we call portable today) external hard drives, users can store innumerous photos, videos, movies and important data on a CD-sized disc.

It can be calculated that this new disc will be equivalent to 20 single-layer Blu-ray discs, 100 DVDs or HDD of a large computer. Well, getting back to holographic storage technology, holograms are 3D patterns that represent bits of information. Unlike the usual DVDs and Blu-ray discs that store information only on the surface, holographic storage technology uses the entire volume of the disc material. However, it offers similarity with the today’s optical storage’s hardware and formats and allows micro-holographic players to playback CDs, DVDs and BDs.

GE has been successful in recording micro-holographic marks with one percent reflectivity and about one micron diameter. On using the usual DVDs or Blu-ray discs, the scaled down marks feature abundant reflectivity to offer more than 500 GB storage space in a single disc.

“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. 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.”

GE’s this demonstration may revolutionize the optical storage industry. This may lead micro-holographic discs capable of storing more than one terabyte information. The GE team is said to be working on the easy adaptability of the technology as well.

“GE’s holographic storage program has turned the corner, and with this milestone we can now intensify our efforts in commercialization opportunities,” said Bill Kernick, who leads GE’s Technology Ventures team. “We’ll continue to engage with a variety of strategic partners to create the best route from product development to introduction into the marketplace.”

GE plans to focus on the commercial archival industry and later on the consumer market to introduce its micro-holographic storage technology.
