Abstract: A method and system for providing head is disclosed. The method and system include providing a first pole, a second pole, a write gap, at least one coil and an Fe3Pt alloy. The write gap separates the first pole from the second pole. The first and second poles are for writing to a medium. The coil(s) have a plurality of turns and reside between the roles. The Fe3Pt alloy is in proximity to the first pole and the second pole. The Fe3Pt alloy is configured to counteract expansion of the first pole and the second pole.

Abstract: An inductive transducer has inorganic nonferromagnetic material disposed in an apex region adjacent to a submicron nonferromagnetic gap in a magnetic core. The inorganic nonferromagnetic material has a much lower coefficient of thermal expansion than that of hardbaked photoresist, reducing pole tip protrusion even if other insulation surrounding the coil sections within the core is made of hardbaked photoresist. Alternatively, the entire insulation surrounding the coil sections within the core, in addition to the apex region, can be formed of inorganic nonferromagnetic material, further reducing pole tip protrusion. The transducer has SiO2 rather than alumina in an undercoat layer joining the wafer substrate and the thin film layers of the transducer. SiO2 may also replace alumina in other areas, such as a piggyback layer joining the inductive transducer with a magnetoresistive transducer.
