The Technological Need for Holographic Data Storage :: Exploratory Essays Research Papers

The Technological Need for holographic Data StorageDigital technology has become the latest byword in entertainment and computers. Records and analog cassette tapes generate been supplanted with Compact Discs, and now VCRs atomic number 18 being challenged by Digital Video Discs. Multimedia applications such as these consume enormous amounts of memory board space, and are challenging the limits of todays terminus devices. numerous another(prenominal) solutions are being put forth in an attempt to glide by pace with the growth in demand for digital selective information storage. some(a) are evolutionary changes in existing media, which can incrementally increase fixedness and capacity, while others attempt to circumvent the limitations of present media by using revolutionary methods, and promise to leapfrog oer conventional technology. Holographic data storage is one of these attempts at creating a new type of high parsimoniousness storage device. However, scientists have been trying to develop a holographic storage device for the past 30 years, when the idea was first proposed. There have been few commercial holographic storage devices released since then, but recent developments in the field and the inertia behind the search for solutions promise to eventually overhear holographic storage a commercially viable reality. Holograms have been somewhat for quite a while. Denis Gabor, a British Physicist, pioneered holographic technology in the 1940s (Glanz 736). In his research, he discovered that, when a place of dogged gently scatters off an object and intersects with another coherent beam, the interference prescript created where the beams cross harbors a three dimensional pictorial matter of the object . . . . The name will reappear when this hologram is probed with a third beam of coherent light (Glanz 736). Thus began the field of holography.Scientists first conceived of using Gabors holograms to store data over thirty years ago. In 1962, IBM instructed Glenn Sincerbox to research using holograms to store data (Glanz 736). The scientists at the time felt, The novel technology holograms promised devices that could pack information 10 times more densely and fetch it 100 times more quickly than could any magnetic disk or tape begin (Gibbs 128). The idea of using holograms to store digital data has been around for many years, and its promises have long been apparent.Holograms are recorded by intersecting an pattern bearing laser beam with a reference beam. The intersection of these beams records the image into the medium which is being recorded on, and the image can then be read later by shining a reference beam at the laser, which then reproduces the original image-bearing wavefront (Heanue, Bashaw, and Hesselink 749).
