摘要： A first trench sidewall has a continuous first taper angle that terminates at a first plane. At least one layer may be deposited that forms a second trench sidewall with a continuous second taper angle that extends a predetermined depth past the first plane and is less than the first taper angle. A write pole may then be formed on the second trench sidewall with the write pole being closer to the first trench sidewall at the predetermined depth than at the first plane.

摘要： An apparatus illustratively includes a return pole (RP) and a shield. The RP has a first RP magnetic layer, a second RP magnetic layer, and a RP non-magnetic layer. The RP non-magnetic layer separates and magnetically decouples the RP first and second magnetic layers. The shield has a first shield magnetic layer, a second shield magnetic layer, and a shield non-magnetic layer. The shield non-magnetic layer separates and magnetically decouples the shield first and second magnetic layers. A method illustratively includes generating magnetic flux and collecting the magnetic flux through an inner magnetic shell.

摘要： A magnetic head having an air bearing surface is used to reduce thermal pole tip protrusion and recession. The magnetic head includes a substrate and a data transducer positioned upon the substrate adjacent the air bearing surface. The data transducer is comprised of a plurality of metallic layers. A compensation structure is positioned adjacent to at least one of the plurality of metallic layers, is exposed at the air bearing surface or recessed at the ABS and extends substantially perpendicular from the air bearing surface. The compensation structure is formed of a material having a coefficient of thermal expansion less than a coefficient of thermal expansion of a material forming the substrate.
