摘要： An assembly comprises a plurality of laterally spaced front blocks, a magnetic post coupling each of the front blocks to a common back bar, and a common front bar magnetically coupled to the back bar. A write gap spacer is positioned between the front bar and each of the plurality of front blocks, and a write gap element comprising write gaps couples the front bar to each front block across the write gap spacer. A coil is configured to generate magnetic flux in each magnetic post, and the front blocks are configured to direct the magnetic flux across the write gaps.

摘要： A method comprises generating first and second magnetic field components in a magnetic medium, the second magnetic field component substantially opposite the first. A pattern is written onto the magnetic medium, and a signal is generated by reading the pattern. The magnitude of the second magnetic field component is controlled based on an asymmetry of the signal.

摘要： A system comprises a magnetic medium with a first magnetic gap adjacent a first side and a second magnetic gap adjacent a second side, opposite the first magnetic gap. The first magnetic gap generates first longitudinal and perpendicular field components. The second magnetic gap generates second longitudinal and perpendicular field components. The first and second longitudinal field components are substantially aligned along a recording layer of the magnetic medium, and the first and second perpendicular field components are substantially opposed across the recording layer of the magnetic medium.

摘要： A system comprises a first tapered core configured for positioning adjacent a first surface of a magnetic medium, and a second tapered core configured for positioning adjacent a second surface of the magnetic medium, opposite the first tapered core along a travel direction of the magnetic medium. Each of the first and second tapered cores has a transverse width defined with respect to the magnetic medium, where the transverse width decreases from a first end of the tapered core to a second end of the tapered core, the second end forming a pole face adjacent the magnetic medium.

摘要： The present disclosure relates to a perpendicular pole head for creating a perpendicular magnetic moment in a concentrated pattern for writing the pattern on perpendicular magnetic media, such as BaFe based media. The pole head can have flux concentrators in the shape of the written pattern, which can be repeatedly applied to a moving magnetic medium to create a timing pattern on the media, e.g., a servo timing pattern.
