    摘要: Holographic data storage systems are fixed after exposure during which data in the form of holograms are stored at locations in the medium (4). Sufficient fixing energy in the form of light or other electromagnetic and thermal radiation is applied to the media (4) either by flooding the media, or to specific locations where the medium has been written. The energy is sufficient to expose the recorded medium (4) to prevent recording in the unused dynamic range thereof. Such recording can be a spurious recording made during readout or from spurious sources of light incident on the media. In one embodiment, the reference beam (108) produced in the course of holographic recording is redirected to locations on the media (4) which have already been recorded. The redirected beam post exposes the media to fix these locations against spurious recording. The integrity of the holographic data storage systems and the robustness thereof is improved by fixing methods and apparatus incorporating the invention.

    摘要: A method of storing and accessing data, comprising:
    sending data from a memory system;
    receiving the data with a read/write holographic drive engine, and writing the data to a holographic recording medium with the read/write holographic drive engine;
    after the data has been written on the holographic recording medium, transferring the holographic recording medium to a read only holographic drive engine medium; and
    reading the data from the holographic recording medium with the read only holographic drive engine.

    摘要: A method and an apparatus for recording at least two multiplexed holograms. The object beam (103) and the reference beam (113) generated by a coherent light source (100). Either an object beam or reference beam is reflected from at least one portion of an aspherical reflecting surface (115) causing the object beam and the reference beam to intersect and form an interference pattern at a plane defined by the intersection of the object and reference beams at a selected storage location (118) in a recording media (116). At least one of a portion of the reference beam impinging on a recording media at the selected storage location and a portion of the object beam impinging on the recording media at the selected storage location is rotated through a selected azimuthal angle about an axis (129) that lies in the plane formed by optical axes of the portions of the object beam and the reference beam impinging on the recording media, wherein the axis passes through a plane defined by the intersection of the object beam and the reference beam in the recording media, and wherein an angle between optical paths of the portions of the object beam and the reference beam impinging on the recording media is preserved.

    摘要: Holographic media (10) for storing and reading holographic data is provided having one or more external surfaces (30, 60) or internal surfaces (61) having structures for at least one of minimizing reflections from illumination incident the surface, or enhancing adhesion between surfaces within the me4dia. Structures for minimizing reflections represent a grating pattern of subwavelength structures providing low reflectivity at the operating characteristics of holographic optical systems to use the media (10), such as spectral bandwidth, angular bandwidth, and polarization of illumination incident the media. Adhesion promotion may be provided by structures along an interior surface of the media (10), such as along an interfacing surface between photosensitive material (12) of the media (10) and a substrate material (11) adjoining the photosensitive material. Such adhesion promotion may be provided by such structured surface with or without providing low reflectivity at the operating characteristics of holographic optical systems to use the media. The structures may be same or similar to one-, two-, or three-dimensional sinusoidal, triangular, staircase, moth eye, pyramidal, lamellar, or binary structures, or combinations thereof, and may be periodic or random.
