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.
