    摘要: A thin-film head has patterned pole tips (68) and a smooth interface topography (70) which eliminates the accumulation of foreign material around the pole tips (68). The patterned pole tips (68) are formed by removing material to obtain a desired pole tip shape. Fill material is added and reduced to produce a smooth surface topography (70).

    摘要: A writer portion of a recording head is disclosed. The writer portion includes a lower magnetic pole. An oxide gap is positioned on the lower magnetic pole. A first insulating layer is positioned on a first portion of the gap oxide, the first insulator layer having a planarized top surface. A plurality of intermediate insulating layers are positioned on top of the first insulating layer. Each intermediate insulating layer encapsulates a layer of conductive coils and has a planarized top surface. A last insulating layer is positioned on top of a portion of the plurality of intermediate insulating layers and on top of a second portion of the gap oxide. An upper magnetic pole is positioned on top of the last insulating layer and on top of a third portion of the gap oxide.

    摘要: A slider includes a magnetic head having first and second magnetic poles separated by a gap. A recess in the air-bearing surface extends into at least the first magnetic pole and has a first portion having a length parallel to the gap length to define a gap width orthogonal to the gap length. The first portion of the recess has a curved depth defining a curved profile along its length. In one embodiment, the recess has a second portion having a length orthogonal to the gap length and a depth defining a curved profile along its length.
