Storing 200 DVD’s On One Polycarb Disc

Editor’s Note: Here’s an interesting gateway into GE Global Research’s endeavors to stuff more and more data into one CD-size disk… right from the horses mouth…

Progress with holographic storage technology
It has been a little while since I wrote an entry in the blog, but I thought I would take a minute to highlight the great progress we continue to make on our efforts to develop holographic storage technology and ultimately to cram as much data as can be put on 200 DVDs onto a single CD-size disc. In fact, we recently had a couple of papers publish on some of our efforts.The first paper was published in the Journal of Applied Physics on July 10th, and described our efforts to improve the performance of our holographic materials. The other paper was published in the journal, Advanced Functional Materials on August 21st and covered a very detailed analysis of one of our early attempts at developing a new holographic material.Both of these articles represent the continued progress that our team is making on these materials, which are a critical piece of the technology. The materials leverage the decades of expertise GE has on traditional optical media materials like polycarbonate.
However, we modify these materials to make them holographic while still maintaining many of the beneficial properties such as the ability to injection mold them into discs (or any shape for that matter!). In addition, an active materials development effort is critical to enabling our systems team to do their magic in developing holographic drives!

Now, you might think that a corporation like GE Global Research would not want to publish results of its work, particularly in cutting-edge fields like holographic storage, but in fact it is quite the contrary. By all means, we are extremely cautious about making sure not to reveal confidential or proprietary information, and sometimes this does mean that we wait to publish important results. But often, publishing results is a critical way to maintain a presence in the community and to build connections with our customers and potential partners. In addition, we recognize the benefit that it brings to our people, enabling us to build a strong technical reputation beyond the walls of GE. It is a delicate balance between being visible to the technical community and keeping critical information under wraps, but it is one that we strive very hard to maintain.
