    Abstract: A method of operating an HDD having a slider-mounted read/write head that is configured for dynamic fly-height operation (DFH) and includes at least one head-disk interference sensor (HDIs). By operating the DFH to lower the head and subjecting the HDIs signal to a power-law enhancement, a consistent and accurate determination of the touchdown power (TDP) can be obtained. Combining absolute TDP determination with a method for measuring relative changes of FH, an absolute determination of FH can be determined.

  • Patent number: 10818319
    Abstract: A read error occurs when performing a read with a first read head. It is determined whether a second read head capable of use in a read-while-write operation runs within or outside of a first track. The second read head width defines a verified area on a track. If the second read head runs entirely within the first track, the first read head is positioned within the verified area. If the second read head runs partly outside of the first track, and a portion of the verified area within the first track is wider than the width of the first read head, the first read head is positioned within the portion of the verified area that is within the first track. If the portion is not wider, the first read head is positioned so that a side of the first read head is at a border the first track.

  • Patent number: 10770102
    Abstract: A tape drive-implemented method, according to one embodiment, includes: using information read from one or more servo bands on a magnetic tape to position a 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 servo readers is positioned at each end of the array of data transducers. 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. Furthermore, the distance between each of the servo readers in each of the groups and the prespecified width are both measured in a direction perpendicular to the direction of travel of the magnetic tape.
