    摘要: A velocity calculator performs high-order calculations of servo frame velocities of a storage media, particularly tape and disk. The velocity calculator employs a servo frame indexing module for generating a first-order preceding servo frame velocity signal indicative of a first-order calculation of a preceding servo frame velocity including a first-order preceding servo frame error term based on first-order current servo frame velocity signal indicative of a first-order calculation of a current servo frame velocity including a first-order current servo frame error term. The velocity calculator further employs a velocity estimating module for generating a higher-order current servo frame velocity signal indicative of a second or higher order velocity calculation of the current servo frame velocity including a higher-order current servo frame error term based on the first-order preceding servo frame velocity signal and the first-order current servo frame velocity signal.

    摘要: Various embodiments for differentiating between data and stubs pointing to a parent copy of deduplicated data are provided. Undeduplicated data is stored with a first cyclic redundancy check (CRC) seed. A stub pointing to the parent copy of the deduplicated data is stored with a second CRC seed. Subsequent to reading the deduplicated data, the first CRC seed is associated with the undeduplicated data, and the second CRC seed is associated with the stub. A CRC check is performed using one of the first and second CRC seeds. If the CRC check is positive, an I/O operation is allowed to proceed. If the CRC check is negative, an additional CRC check is performed using another one of the first and second CRC seeds.

    摘要: A magnetic storage media has a servo track segment and a timing based servo band recorded on the servo track segment. The timing based servo band includes a modulated timing based servo pattern string representative of magnetic encoded servo position information for facilitating a determination of a servo position error signal. Exemplary forms of the modulation of the timing based servo pattern string includes a pattern interspacing modulation, a magnetic intensity modulation, and a pulse position modulation.

    摘要: An apparatus, system, and method are disclosed for hard disk drive redundancy. A demarcation module demarks a parity data block in each set of a specified number of data blocks on a hard disk drive. An association module associates a PBA of each un-demarked data block with a LBA. A write module writes the data to the un-demarked data blocks. A parity module calculates parity data for the data written to the un-demarked data blocks and the write module writes the parity data to the parity data block.
