    摘要: A data processing system having a flexible internal structure, protected from and effecitvely invisible to users, with multilevel control and stack mechanisms and capability of performing multiple, concurrent operations, and providing a flexible, simplified interface to users. The system is internally comprised of a plurality of separate, independent processors, each having a separate microinstruction control and at least one separate, independent port to a central communications and memory node. The communications and memory node is an independent processor having separate, independent microinstruction control and comprised of a plurality of independently operating, microinstruction controlled processors capable of performing multiple, concurrent memory and communications operations. Addressing mechanisms allow permanent, unique identification of information and an extremely large address space accessible and common to all such systems. Addresses are independent of system physical configuration. Information is identified to bit granular level and to information type and format. Protection mechanisms provide variable access rights associated with individual bodies of information. User language instructions are transformed into dialect coded, uniform, intermediate level instructions to provide equal facility of execution for all user languages. Operands are referred to by uniform format names which are transformed, by internal mechanisms transparent to users, into addresses.

    摘要: A tape cartridge (12) is provided for storing holographic recordings in a longitudinal holographic storage media tape (14). The tape (14) is comprised of a thin holographic storage media such as a photopolymer. A laser (54) is operable to generate a coherent light beam, which is then positioned on a given row of storage regions (42) on the surface of the tape (14). A positioning/angle multiplexing device (90) is operable to both position a reference beam (60) and a data beam (62) onto a select one of the storage regions in a given row on the surface of the tape (14). The tape (14) is incremented a row at a time for each scan operation wherein both the reference and the data beams during a Write operation, and only the reference beam during the playback operation, are moved along a given row. The spinning polygon mirror (56) is utilized to provide both positioning along a given row and angle multiplexing in a select storage region, with the optic system removing the angular information from the data beam (62). Data is superimposed on the data beam by an SLM (76).

    摘要: A holographic storage media (10) is fabricated from a thin layer of photopolymer recording media. The photopolymer recording media is disposed between a substrate (48) and a capping layer (56). The media (10) is divided into a plurality of storage regions (54), which are formed within wells (52) to isolate each of the regions (54). During a record operation, a pumping operation is first performed to remove oxygen molecules from the media by bombarding the select region that is to have an interference pattern recorded therein with photons for a predetermined duration of time. Once the oxygen molecules have been depleted, then a data beam is generated with data superimposed thereon and a reference beam generated for interference with the data beam in the storage region (54). This results in the recording of an interference pattern.

    摘要: An apparatus for positioning a data and reference beam onto the surface of a holographic storage media (10) includes a laser (16) for generating the reference beam, and a first reflecting surface (18) for positioning the output of the laser (16) along the y-axis. The beam is split into a data beam and a reference beam by a beam splitter (24) with the data beam directed toward an SLM (36) and the reference beam (26) directed toward an angle multiplexing reflective surface (40). The data beam during a record operation is reflected from the surface of the SLM (36) to a transform lens (34) and then to a column (35) on the surface of a holographic storage media (10). The reference beam is reflected from a reflective surface (40) at a predetermined angle determined by the position of the reflective surface (40) to an HOE (46) for redirection to the surface of the storage media (10) to interfere with the data beam. During a data reconstruction operation, only the reference beam is generated. This results in a reconstructed image being directed toward an imaging lens (52) and then to a detector (54).

    摘要: A holographic storage assembly is provided which utilizes a large holographic storage media (36) disposed between two reflecting surfaces (40) and (42). An optics system (44) is disposed between the two reflecting surfaces (40) and (42) is operable to generate both a reference beam (58) and a data beam (50). The data beam (50) and reference beam (58) are generated on a virtual spot plane (100), which is then imaged from the surface of the reflecting surface (42) onto the much larger surface of the media (36). This is operable to record an interference grating at a storage location (56). During a playback operation, a reconstructed data beam (64) is generated and reflected from the surface of the mirror (40) onto a detector (68) in the deflector system (44).
