    摘要： According to one aspect and example, a holographic recording system includes a light source, an object for modulating an object beam from the light source, and a relay system adapted to magnify (positive or negative) the modulated beam (e.g., an image of the object) to an output image. The object may include an SLM operable to modulate the object beam with an information layer comprising a plurality of data pages. The output image is directed to the holographic storage medium, where a reference beam is also directed, to record the resulting interference pattern. Additionally, the relay system converges the output image to an output Fourier plane, which may be disposed within the holographic storage medium. A filter may be placed at an intermediate Fourier plane located prior to the output Fourier plane, and a phase mask may be placed at the position of the output image.

    摘要： According to one aspect and example, a method for recording holographic media and/or holographic master data masks includes recording at least a first hologram or information layer with a first holographic medium (e.g., a “submaster”) and recording at least a second information layer with a second holographic medium (e.g., a second “submaster”). The first information layer and the second information layer from the first and second holographic media are then sequentially reconstructed and stored with a single holographic master medium (e.g., a “master”). The holographic master may then be used to record the stored first and second information layers into additional holographic media, for example, into HROM devices or the like.

    摘要： A method is provided for manufacturing a holographic medium by recording holograms in transmission geometry, and applying a reflective layer to one side of the holographic recording material after recording is completed (alternatively, for example, the playback system may contain a reflective surface or mirror). For readout, the reference beam is incident to the media from a side opposite the reflective layer. This beam propagates through the media to the reflective layer on the opposite side, and is reflected back through the media for readout of the transmission hologram. The diffracted hologram signal also exits the media on the side without the reflective layer, where it can be recovered by a detector on the same side as the laser source. Alternatively, the readout reference beam is positioned so that the incident beam reads out the hologram, and both the reference beam and diffracted hologram are reflected back through the media.

    摘要： A holographic disc recording medium records a hologram over the entire holographic disc recording medium by using a conical reference beam for recording. A hologram recorded image includes recorded images of a plurality of data pages including a plurality of pixels arranged in an approximately rectangular array. A cylindrical reference beam for reading having coherent light having an approximately cylindrical wavefront shape with a small curvature is used to minimize the mismatch in wavefront shapes between the reference beam for recording and reference beam for reading.

    摘要： A holographic disc recording system for recording, in the form of holograms, information stored on a source disc onto a target disc includes a conical beam shaper which transforms a reference beam into a conical beam having a substantially cylindrically symmetrical shape and including light rays which travel along lines which intersect a beam axis of the conical beam at substantially the same angle with respect to the beam axis. The conical beam is incident on the target disc while the beam axis of the conical beam substantially coincides with a central axis of the target disc, so that substantially all of the light rays of the conical beam are incident on the target disc at substantially the same angle.

    摘要： For encoding a current data word to be encoded, a most suitable redundant signal for the current data word to be encoded is generated by referring to a next data word to be encoded, that is, using a look-ahead decision method. The current data word to be encoded is encoded by using this redundant signal. A low-frequency component of the encoded data is effectively suppressed without decreasing encoding efficiency, by using both a regular substitution code and a stochastic substitution code, and a look-ahead determination algorithm for changing the length of words of a data segment, based on stochastic occurrence of a substitution word.
