If that Blu-Ray looks too small….Sunday, May 3rd, 2009 by Roberto Saracco
General Electric has announced a microholographic disc that can store 500 GB of data (a Blu Ray store “only” 50 GB). The one announced is just a lab prototype but they expect a product to hit the market in 2012 at a cost of less than 10c a GB. This can be the next generation of optical disc.
Blu ray, as DVD, stores bits in tiny holes on the surface of the disc, each one corresponding to a 0 or 1. On the contrary, with holographic technology the bits are stored as interference pattern and there can be many bits stored in the space that was before required to store just one.
Holographic storage is not new: InPhase Technologies has a product on the market but it is too expensive to hit the mass market. The GE technology promises to cut the cost dramatically thus making it affordable and viable to consumers.
We can expect to see a need for this kind of storage in our homes early in the next decade as many moments of our life will be captured in bits.
