Abstract: Approaches for a magnetic write head having an adjacent coil architecture, wherein a coil turn is fabricated immediately adjacent to the writer main pole. The adjacent coil portion essentially lies on the main pole, except for a very thin layer of insulation atomically layered in between. The adjacent coil portion is also substantially closer to the wrap-around shield in comparison with conventional coil configurations. Further, the other upper coil portions may be fabricated to essentially lie on the stitch pole, again except for a very thin atomic layer deposited layer of insulation layered between. This adjacent coil configuration provides a writer coil configuration that concentrates the coil structure significantly closer to the main pole surface, as well as concentrates more of the coil structure closer to the main pole tip, providing for a more efficient and faster write head.

Abstract: A magnetic head includes a plurality of coil elements disposed in a space defined by a lower core layer, a pole layer, and a back gap layer. A coil insulator fills the space so as to cover the coil elements. The top face of the pole layer, the top face of the coil insulator, the top faces of the coil elements, and the top face of the back gap layer form a planarized plane. The coil elements are disposed on a recess formed on the lower core layer. The bottom faces of the coil elements are disposed at substantially the same height as the top face of the lower core layer. The top faces of the coil elements lie in the planarized plane.
