commercialization of holographic data storage

CDs, DVDs, and magnetic storage encode data as discrete bits across the surface of the storage media. In contrast, Holotech data storage stores information permeating the three- dimensional thickness of storage media. Holotech information storage and extraction systems also create the opportunity for extensive parallel processing in storage and retrieval because such systems store and read complete pages (possible a million bytes) at once rather than linear series of data bits. Investigators have been pursuing holographic data storage systems for decades. However, it has only been during recent years that vital breakthroughs in substances and technological applications have made them consumer marketly feasible. For instance, relatively inexpensive liquid crystal displays and integrated circuits have contributed to reduce the cost of holotechnology data storage. There is considerable research being done by a quantity of research laboratories toward the consumer marketization of volumetric holographic digital data storage. Further, Holograms 3D Holographic Projection covers holotech related technologies.

To encode the image of an object using holographic applied science, the signal beam is shown through an expander lens onto the target item and then bounced off the object into three-dimensional, photosensitive optical media (especially a polymer or crystal) where it crosses with a reference ray. The resulting interference pattern between the reference and signal rays inside the photosensitive media makes chemical reactions that engrave the holographic picture in the storage material. To retrieve the holotechnology picture, a reference beam is shown on the hologaphically encoded photosensitive material with the identical angle and wavelength previously used to engrave the source hologram. This initiates refraction within the storage material and recreates the holotechnology image three dimensionally outside the media. The holographic picture appears three dimensionally due to observed parallax. Virt Phones provides further information on holotech and these topics.
