Holographic technology involves true 3-D recording of information. The dealer frame components consist of a laser, a Spatial dismay Modulator (SLM), memory board media, detector and transform optics. Fig. 1 exposit schematically the elements of holographic recording and empathise out of info. information argon stored holographically by recording in the storage mass medium the optical affray form that is created by mixing an encoded data ventilate with a perspicuous reference quill. The data be conveniently encoded as level binary rogues of bright and evil spots (corresponding to the 1s and 0s of the digital data) exploitation a SLM, a device that acts as a order of independent light valves. For read out, a laser station equivalent to the reference beam is projected onto the put down interference pattern in the media, and the diffracted beam carrying the reconstructed data page is imaged onto a detector. In the mercenary product, lasers will interact with g yrate disk media similarly to CD or DVD systems. very high data densities (>100 bits per public squ are micron versus about 10 bits/sq. micron for most magnetized hard drive products) are achieved by optically multiplexing the enter pages, allowing numerous pages to be stored at bottom a maven small spatial region of the media.
The baron to multiplex recorded pages is derived from use of the thickness (3rd dimension) of the media. Consequently, CAPACITIES OF >100 GB atomic number 18 ACHIEVABLE in half-millimeter thick media IN A streamer 5.25-inch DIAMETER DISK FORMAT for our introductory products. Addition ally, data rank can be significantly enhanc! ed since data are stored and canalisered as pages of information (ca. 1 million bits per page), compared with sequential polish off of single bits from conventional storage technologies. DATA RATES OF >750 MB/sec ARE POSSIBLE FROM A SINGLE HEAD. If you want to get a full essay, order it on our website:
