    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.

    摘要: A method is disclosed to store and retrieve information using holographic data storage media. The method provides original data, generates a first image of that original data, and encodes that first image in a holographic data storage medium at a first storage location. The method then generates a second image of the original data, where the second image differs from the first image, and encodes the second image in a holographic data storage medium at a second storage location, where the second storage location differs from the first storage location.

    摘要: A method is disclosed to determine an optimal power level to encode information holographically. The method sets (N) evaluation power levels, displays an evaluation image on a spatial light modulator. For each value of (i), the method energizes a light source using the (i)th power level, generates the (i)th reference beam, generates the (i)th carrier beam, forms the (i)th data beam comprising the evaluation image, forms the (i)th hologram using the (i)th reference beam and the (i)th data beam, and encodes the (i)th hologram in a holographic data storage medium, where (i) is greater than or equal to 1 and less than or equal to (N).

    摘要: A holographic storage drive and control of a holographic storage system are configured to write at least a group of holograms in a predetermined pattern in the holographic storage medium, and to write a directory hologram which relates to the holograms of the group to form an anchor location of the predetermined pattern. Further, a directory comprising the directory hologram stored in a memory, and the control is configured to initiate a read operation of at least one hologram of a group with an access for the directory hologram of the group at the anchor location; to read the accessed hologram, employing a matched filter to cross-correlate the read accessed hologram with an ideal version of the directory hologram derived from the directory stored in the memory; and to determine whether the read accessed hologram is the directory hologram of the group.
