GE Holographic Data Storage Project: Burn 20 Blu-Ray Or 100 DVDs In Single Disc

Engineers at General Electric (GE) have achieved a breakthrough in the Holographic Data Storage Project. The team of researchers demonstrated a micro-holographic material which supports recording of data at the speed of Blu-Ray discs. This means, in future we'll be able to burn 20 Blu-Ray discs (100 DVDs) in a single disc of the same size as DVD. The new technology developed by GE has a potential to bring revolution in the high-capacity data storage domain. This domain is currently dominated by optical and magnetic data storage. The holographic data storage offers a challenging technical problem that requires experts from the field of Chemistry, Optics and Electrical Engineering. GE Global Research is one of the best research places to bring all the domain experts together. The research team has achieved several breakthroughs in the recent past. In 2006, the team demonstrated threshold behavior in holographic materials. In 2009, the team demonstrated that storing 500 GB data in single disc was possible with the use of 'high reflectivity' property of holographic material.

The commercial viability of the micro holographic data storage is judged by two important parameters. First is the hologram reflectivity and material sensitivity and second is the ease of handling the material and processing it to get the form of disc. Hologram sensitivity directly affects the data recording speed; higher the sensitivity - faster is the recording speed. Researchers have achieved 100 times more sensitivity in holographic material thereby boosting the recording speeds. Initial test results have showed that the data transfer rate is quite bigger than the conventional optical discs.
