    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 writes at least a group of holograms in a predetermined pattern in the holographic storage medium, and writes 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 is stored in a memory, and a read operation of at least one hologram of a group is initiated with an access for the directory hologram of the group at the anchor location; reading 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 determining whether the read accessed hologram is the directory hologram of the group.

    摘要: Data hologram recycling systems, methods and computer program products are configured to arrange data for storage in the intermediate data storage as data segments which are replicas of holographic storage segments for destaging to the holographic data storage, and to determine retrieval for recycling of the destaged holographic storage segments to which aggregated requests for deletion are directed. The retrieval determination may be based on a plurality of policies.
