    摘要： A multi-sensor reader that includes a first sensor that has a sensing layer with a magnetization that changes according to an external magnetic field. The first sensor also includes first and second side biasing magnets having a magnetization substantially along a first direction. The first and second side biasing magnets align the magnetization of the sensing layer substantially along the first direction when the sensing layer is not substantially influenced by the external magnetic field. The multi-sensor reader further includes a second sensor that is stacked over the first sensor. The second sensor includes a reference layer that has a magnetization that is set substantially along a second direction. The first sensor further includes at least one sensor-stabilization feature that counteracts an influence of a magnetic field utilized to set the magnetization of the reference layer of the second sensor in the second direction on the magnetization of at least one of the first and second side biasing magnets in the first direction.

    摘要： A de-swage machine for removal of a head of a head stack assembly including a tooling unit configured to receive a head stack assembly comprising a plurality of heads and an indicia, a blade module configured to remove a head from the head stack assembly, an indicia reader configured to read the indicia, and a controller. The controller is configured to select and remove a head from the head stack assembly by at least reading the indicia using the indicia reader, transmitting the indicia to a database, receiving head stack assembly information corresponding to the indicia from the database, selecting the head for removal based on the head stack assembly information, and removing the selected head using the blade module. The blade module can also include a force sensor, and the de-swage machine can also include an imaging unit.

    摘要： A head gimbal assembly for a disk drive includes a flexure tail terminal region having flexure bond pads in electrical communication with the head. Each of the flexure bond pads includes a widened region of a corresponding one of a plurality of electrical traces in a conductive layer, and a discontinuous bond pad backing island in a structural layer that overlaps the widened region. The flexure tail terminal region also includes a plurality of discontinuous edge stiffener islands in the structural layer that do not overlap the widened region of any flexure bond pad, and that are disposed no more than 50 microns from one of the two opposing longitudinal outer edges of the flexure tail terminal region. At least one of the plurality of discontinuous bond pad backing islands is disposed no more than 50 microns from one of the two opposing longitudinal outer edges.

    摘要： A method for manufacturing a magnetic core module in a magnetic head, the magnetic core module and the magnetic head. The method for manufacturing the magnetic core module includes: a process for placing a magnetic core group in a holder mold cavity as an insert; and a process for injection-molding in the holder mold cavity. A method for manufacturing the magnetic core module allows the magnetic core group and the holder to be integrally injection-molded with a method of injection molding which uses the magnetic core group as an insert. The method simplifies the process of manufacturing a magnetic head to improve production efficiency, and saves labor and production costs. Further, the method prevents failures such as positional displacement and scattering of magnetic cores, which tends to occur when assembling thin and small magnetic cores, and ensures an ideal yield for a product.
