    摘要: A method for performing write calibrations on holographic storage media is disclosed. Initially, five identical and known calibration holograms are written on a holographic storage medium, in which three of the five calibration holograms are written with different laser power and three of the five calibration holograms are written with different time durations. A matched filter is then utilized to determine a cross-correlation between the five calibration holograms read from the holographic storage medium and their corresponding ideal calibration holograms previously stored within a memory device within the holographic storage drive. A least-squares fit of an ellipsoidal parabola to the cross-correlations is subsequently calculated to yield an optimal laser write power level and an optimal duration for a laser write pulse.

    摘要: A holographic disc comprises a multilayer right-circular frustum. The frustum includes a substrate layer having an inner surface and an outer surface. A reflective track layer is formed on the inner surface of the substrate layer. A first gap layer overlies the reflective track layer. A dichroic mirror layer overlies the first gap layer. A second gap layer overlies the dichroic mirror layer. A holographic recording layer overlies the second gap layer. A cover layer overlies the holographic recording layer. The cover layer has an inner surface in contact with the holographic recording layer and an outer surface. The frustum has a major diameter and a minor diameter. In one embodiment of the multilayer right-circular frustum, the outer surface of the said outer surface of the cover layer defines the minor diameter and the outer surface of the substrate layer defines the major. In another embodiment, the outer surface of the substrate layer defines the minor diameter and the outer surface of said the cover layer defines the major diameter.

    摘要: A holographic storage drive of a holographic data storage system is configured to write and read holograms with respect to a plurality of locations of a holographic storage medium; and a control is configured to operate the holographic storage drive to write a known image aggregated with data in the form of a hologram to the holographic storage medium; to operate the holographic storage drive to read back the written hologram, employing a partial matched filter to cross-correlate the read-back image with the ideal version of the known image, excluding the remainder of the written hologram; and to determine whether the cross-correlation at least meets a write/readback threshold.

    摘要: A method to sequentially deduplicate data, wherein the method receives a plurality of computer files, wherein each of the plurality of computer files comprises a label comprising a file name, a file type, a version number, and file size, and stores that plurality of computer files in a deduplication queue. The method then identifies a subset of the plurality of computer files, wherein each file of the subset comprises the same file name but a different version number, and wherein the subset comprises a maximum count of version numbers, and wherein the subset comprises a portion of the plurality of computer files. The method deduplicates the subset using a hash algorithm, and removes the subset from said deduplication queue.
