    摘要： A method according to one embodiment includes forming a first portion of a thin film writer structure on a substrate, forming a portion of a write gap at an initial position, a plane of deposition of the portion of the write gap being at an angle of greater than 0° and less than 90° relative to an upper surface of the first portion in the initial position, moving the writer structure to orient the plane of deposition of the portion of the write gap more toward perpendicular to a plane corresponding to a final media-facing surface of the writer structure than the orientation of the plane of deposition of the portion of the write gap in the initial position, and fixing the writer structure in place after the moving.

    摘要： An apparatus according to one embodiment includes a module having first and second transducers of different transducer types positioned towards a media facing side of the module, where the different transducer types are selected from a group consisting of data reader transducers, servo reader transducers, write transducers, piggyback read-write transducers and merged read-write transducers. The apparatus also includes a first protection structure for protecting the first transducer. The second transducer has either no protection or is protected by a second protection structure that is different than the first protection structure. In one embodiment, the first protection structure includes a coating on the media facing side of the module adjacent the first transducer. In another embodiment, the first protection structure is a recessed portion of the media facing side adjacent the first transducer.

    摘要： In response to determining that a first write operation is to be performed on a portion of tape, writing data to a data track with a tape head element spacing at a nominal value. A tape width of one or more tape positions at which data is written is recorded. In another aspect, a tape width value associated with a tape is retrieved. A current tape width value associated with the tape is determined, and the tape head element spacing is set based on a difference between the retrieved tape width value and the determined current tape width value.

    摘要： Recording a servo write head spacing for writing servo tracks on a magnetic tape in a manufacturing environment. One or more environmental condition measurements of the manufacturing environment are received by a computer. A pair of servo tracks is written on a magnetic tape by a pair of servo write heads at a nominal spacing. The one or more environmental condition measurements of the manufacturing environment and information pertaining to the spacing of the servo tracks on the magnetic tape are recorded in one or more data stores.

    摘要： A thin film inductor with top and bottom pole pieces that are mechanically connected to each other at at least two via zones, to create a magnetically permeable yoke that defines at least one interior space. Enclosed portion(s) of a winding member pass through the interior space(s) of the yoke. The enclosed portion(s) of the winding member define an axial direction and a transverse direction. The pole pieces extend beyond the via zones in the axial and/or transverse direction. The extended pole pieces improve magnetic performance of the thin film inductor, by effectively moving pole piece edges away from locations of high magnetic flux density.
