  • Method of total dimensional stability control in magnetic tape system with global calibration data
    Patent number: 11741993
    Abstract: A method for generating calibration data useful for calibrating a plurality of tape cartridges includes the steps of selecting a subset of tape cartridges from the plurality of tape cartridges, the subset of tape cartridges having fewer tape cartridges than the plurality of tape cartridges; calibrating each of the subset of tape cartridges using a plurality of tape drives to generate global calibration data; selecting one of the plurality of tape cartridges that is not included within the subset of tape cartridges; and calibrating the one of the plurality of tape cartridges using the global calibration data generated via the calibrating of each of the subset of tape cartridges.

  • End-to-end fixity check for archival storage based on high-performance integrity test with data quality using self-describing tape format
    Patent number: 11615813
    Abstract: A method for ensuring data quality integrity on a magnetic tape includes the steps of writing object data to the magnetic tape; dividing the object data into a plurality of data chunks; generating a hash tree from the plurality of data chunks, the hash tree being formed in a plurality of levels, the hash tree including (i) a plurality of chunk hashes wherein a separate chunk hash is generated for each of the plurality of data chunks, and (ii) at least one second level hash that is generated from concatenation of at least two of the plurality of chunk hashes; and checking integrity of a first data chunk of the plurality of data chunks by evaluating at least one of the plurality of chunk hashes and the at least one second level hash.
