摘要： A magnetic head includes a slider body having a trailing surface meeting an air-bearing surface at a trailing edge and a thin-film transducer that includes a magnetic reproducing element with a magnetoresistive (MR) element disposed near the trailing edge within a gap material bounded by upper and lower shield layers. The thin-film transducer also includes a lower pole layer of a magnetic recording element disposed in a first general plane. The magnetic recording element further includes a coil having first and second turn layers disposed in second and third general planes, respectively. The magnetic head also includes resistive heating element with at least a portion of the heating element being disposed in a fourth general plane beneath both the lower pole layer and the coil but above the upper shield layer. Current flow through the heating element causes expansion of the magnetic reproducing and recording elements at the ABS.

摘要： A head including a write element for writing data to a magnetic media, and methods for its production are provided. A write element of the invention includes one or more of a recessed first pole, a heat sink layer, and a shortened yoke length. A method of the invention provides forming an anti-reflective layer before forming a mask layer. During photolithography the anti-reflective layer suppresses undesirable reflections off of features, such as vertical sidewalls, that otherwise limit how closely to such features portions of the mask layer can be formed.

摘要： A method of making a perpendicular magnetic recording head for use in a data storage device includes forming a first pole layer, a second pole layer, a third pole layer, and a shield layer of a write section. The first pole layer, second pole layer, third pole layer, and shield layer are formed without using a chemical mechanical polishing process. The method next includes concurrently trimming the shield layer and a write pole that is defined by the third pole layer to a predetermined track width. In the trimming step, the shield layer is used as a mask for the write pole.
