A data storage cartridge comprises data storage media configured to store data for read and/or write access, wherein the data may be arranged in a plurality of partitions; and a plurality of cartridge memories. A control system, for example of a data storage drive, is configured to allocate at least portions of capacity of the data storage media to cartridge memories of the data storage cartridge; and to provide information defining the allocated portions of capacity to the cartridge memories. Each of the cartridge memories may have a separate user and thus provide access for that user to separate partitions.

A data storage cartridge comprises data storage media configured to store data for read and/or write access, wherein the data may be arranged in a plurality of partitions; and a plurality of cartridge memories. Each cartridge memory comprises a communication interface and a memory, wherein the information of the memory is formatted to allow association with at least one of the plurality of partitions of the data storage media. Thus, each of the cartridge memories may have a separate user and provide access for that user to a separate partition or subset of partitions.

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 provide data storage services using one or more holographic data storage media disposed in a holographic data storage system operated by a data storage services provider, wherein the holographic data storage system comprises a light source, a spatial light modulator, and a plurality of holographic data storage media, wherein the method receives information provided by the data storage services customer, allocates a first holographic data storage medium for exclusive storage of information provided by the data storage services customer, defines an outer storage portion of the first allocated holographic data storage medium, and stores the information as one or more holograms encoded in the outer storage portion of the first holographic data storage medium.

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.
