Title: Servo write head having plural spaced front blocks coupled by magnetic posts to a back bar

Abstract: 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.
