摘要： The present techniques provide methods and systems for recording micro-holograms on a holographic disk using a plurality of counter-propagating light beams in parallel. The parallel counter-propagating light beams overlap to form interference patterns on a data layer and over multiple data tracks in the holographic disk. Rotating the disk enables the parallel recording of micro-holograms over multiple data tracks, thus reducing recording time. Further, the illumination pattern may include illuminated spots and non-illuminated regions, such that each illumination spot may cover a relatively small fraction of the data layer plane, possibly controlling the depth spread of the recorded micro-hologram. In some embodiments, data in the parallel signal beams may be retrieved from a master holographic disk or may be modulated into the parallel signal beams.

摘要： The present techniques provide methods and systems for controlling the recording of micro-holograms using multiple counter-propagating light beams over multiple data tracks of a holographic disk. Imperfections in a holographic disk or movement of the disk during a recording process may cause signal beams to deviate from target data tracks. In some embodiments, a tracking beam is directed to a reference layer in the disk. Deviation of the reference beam from a target groove in the reference layer may be indicative of tracking errors. A detector may detect reflections of the tracking beam and generate an error signal in response to detected tracking errors. Servo-mechanical devices may actuate (e.g., radially, tangentially, or axially translate, rotate, and/or tilt) one or more optical components through which the counter-propagating light beams are emitted to compensate for tracking errors.

摘要： Techniques are provided for controlling the reading of optical data from a master disk in a holographic replication system. Imperfections in the master disk or movement of the disk during a recording process may cause source beams to deviate from target data tracks. In some embodiments, a detector system is used to determine the focus and alignment of the source beams on the master disk, as well as the tilt and rotation of the disk with respect to the holographic replication system. The detector system may detect deviations in the intensity distribution of the reflections of the source beams and generate an error signal corresponding to focusing, tracking, tilt, and/or rotational errors. Servo-mechanical devices may actuate optical components to compensate for such errors.

摘要： Techniques are provided for increasing storage capacity in a holographic storage system. While typical holographic storage systems involve binary storage for each data position in a holographic disk, present techniques involve storing data such that more than two data levels may be recorded in each data position. In some embodiments, a recording beam directed to the disk may be adjusted to different power levels depending on the data level to be recorded. Furthermore, the recording time at a data position may be adjusted to increase the energy directed to the data position by increasing the amount of time the recording beam is impinged on the data position. Embodiments are suitable for different types of holographic storage, including dye-based medium.

摘要： A method for calculation of recording depth in a holographic disk is disclosed. The method includes applying a first external voltage to one or more actuators coupled to an objective lens to focus a tracking beam of radiation having a first wavelength on a reference layer of the disk, wherein the reference layer comprises at least one of a partially dichroic coating or a partially metallized coating. The method also includes applying a second external voltage to the one or more actuators coupled to the objective lens to focus a recording beam of radiation on the reference layer of the disk, wherein the recording beam comprises a second wavelength different from the first wavelength of the tracking beam. The method further includes computing a difference between the first external voltage and the second external voltage. The method also includes calculating a lens-shift distance based upon the difference using a voltage-distance calibration curve, wherein the lens-shift distance refers to a shift in distance of the objective lens in order to focus the tracking beam of radiation and the recording beam of radiation on the reference layer respectively. The method also calculates the recording depth based upon the lens-shift distance.

摘要： The present techniques provide methods and systems reading a data bit of interest on an optical data disc with a reduced error rate. The data bit estimation may be improved by reducing deterministic noise resulting from an optical reader system and/or the optical data disc. The reader may adjust the position of a detector to detect light scattered from the disc based on parameters of known noise sources. In one embodiment, the detector may be moved vertically in relation to the data bit of interest on the optical disc. In another embodiment, more than one detector may be used to detect light scattered from a data bit of interest. In embodiments, the positioning of the detector(s) may be based on system or disc parameters, and the detected scatterings may provide a data reading, improved for an optical return from a present micro-hologram.
