| Abstract | In holographic data storage an entire page of information, up to one a million bits in one single page, is stored at once as an interference pattern within a thick, photosensitive optical material. This inherent parallelism allows for data rates in excess of one Gb/s. A large number of these interference patterns can be stored in the same microscopic piece of media as long as they are distinguishable by their direction or the spacing of these gratings. The theoretical limits for the storage density of this technique are around tens ofTerabits per cubic centimeter. In addition to high storage density and high data rate, holographic data storage promises fast access times, because the laser beams can in principle be moved rapidly without inertia, unlike the actuators in disk drives. But despite of all of these obvious advantages and the general availability of relatively low-cost components, such as liquid crystal displays for spatial light modulators and CCD camera chips from video recorders for detector arrays, no commercial holographic storage products are available today. Why? And when is this going to change? |
