摘要： Methods and systems are provided for recording micro-holograms in a holographic disk 10. Disk tilting or disk imperfections may cause counter-propagating recording and reference beams to deviate from the target data position in the disk 10. In some embodiments, a tracking beam is directed to a tracking position in the disk, and deviation of the tracking beam from the tracking position may indicate tracking and/or focusing errors of the recording and/or reference beams. A detector 38 may generate an error signal in response to such errors. A first servo-mechanical system 28 may actuate a first optical head (e.g., transmitting the reference and tracking beams) to compensate for such errors, and a second servo-mechanical system 32 may actuate a second optical head (e.g., transmitting the recording beam) to follow the actuation of the first servo system, such that an interference of the reference beam and the recording beam may be maintained in the target data position.

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 at different positions (66,68,70) in a data layer (60). 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： Techniques are provided for controlling the reading of optical data 10 from a master disk 46 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 38 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 38 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 28 may actuate optical components to compensate for such errors.

摘要： A method for calculation of recording depth in a holographic disk 10 is disclosed. The method includes applying a first external voltage to one or more actuators coupled to an objective lens 82 to focus a tracking beam of radiation 76 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 112 coupled to the objective lens 82 to focus a recording beam 96 of radiation on the reference layer of the disk 10, wherein the recording beam 96 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 82 in order to focus the tracking beam of radiation 76 and the recording beam of radiation 96 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 for controlling the recording of micro-holograms 68 using multiple counter-propagating light beams over multiple data tracks 12 of a holographic disk 10. Imperfections in a holographic disk 10 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 22 is directed to a reference layer 78 in the disk. Deviation of the reference beam 66 from a target groove in the reference layer 78 may be indicative of tracking errors. A detector may detect reflections of the tracking beam 22 and generate an error signal in response to detected tracking errors. Servo-mechanical devices 28 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.
