Patent number: 10262681Abstract: According to one embodiment, a system includes a controller configured to determine whether a position error signal (PES) is invalid while reading data from a magnetic medium using at least one data channel. An invalid PES indicates off-track reading or a defect in the magnetic medium. The controller is also configured to determine whether a PES value is above a first predetermined threshold in response to a determination that the PES is valid. Moreover, the controller is configured to inject error bits into a data stream in place of corresponding bits of decoded data in response to a determination that the PES is invalid, a determination that the PES value is above the first predetermined threshold, or a determination that the PES is invalid and the PES value is above the first predetermined threshold. Other systems and methods are described in accordance with more embodiments.Type: GrantFiled: November 28, 2017Date of Patent: April 16, 2019Assignee: International Business Machines CorporationInventors: Nhan X.

Patent number: 9997184Abstract: A tape drive-implemented method, according to one embodiment, includes: determining a servo band configuration of servo bands on a magnetic tape, using servo readers on a magnetic tape head to read one or more of the servo bands based on the determined servo band configuration, and using information read from the one or more of the servo bands to position the magnetic tape head relative to the magnetic tape. An array of data transducers is positioned along the magnetic tape head, the array extending perpendicular to a direction of travel of the magnetic tape. Moreover, a group of the servo readers is positioned at each end of the array of data transducers, and a distance between each of the immediately adjacent servo readers in each of the groups of servo readers is less than or equal to one third of a prespecified width of each of the servo bands.Type: GrantFiled: November 9, 2017Date of Patent: June 12, 2018Assignee: International Business Machines CorporationInventors: Nhan X.

Patent number: 9959892Abstract: Some embodiments of the present invention logically eliminate an end region of a user-data area of a magnetic storage tape during formatting (or re-formatting) of the tape, if the position error signal (PES) variance corresponding to the end region exceeds a threshold. An adjacent region, having a PES variance less than the threshold is designated as a new end region, thereby shortening the user-data area of the tape and extending its usable life.Type: GrantFiled: May 12, 2017Date of Patent: May 1, 2018Assignee: International Business Machines CorporationInventors: Tsuyoshi Miyamura, Kazuhiro Tsuruta, Eiji Ogura, Tomoko Taketomi

Patent number: 9934816Abstract: For avoiding debris accumulation on a tape drive, a processor records a position error signal (PES) value and cumulative head turnaround count for each region of a plurality of regions of a magnetic tape. The processor further selects a first region in which to reverse travel of the magnetic tape relative to a tape head. In response to determining one of the PES value for the first region does not exceed a PES threshold and the cumulative head turnaround count for the first region does not exceed a count threshold, the processor reverses travel of the magnetic tape at the first region. In response to determining the PES value for the first region exceeds the PES threshold and the cumulative head turnaround count for the first region exceeds the count threshold, the processor selects a second region at which to reverse travel of the magnetic tape.Type: GrantFiled: February 6, 2017Date of Patent: April 3, 2018Assignee: International Business Machines CorporationInventors: Tsuyoshi Miyamura, Eiji Ogura, Tomoko Taketomi, Kazuhiro Tsuruta
