摘要： A method of manufacturing a magnetic head, including a magneto resistance effect (MR) element that reads a magnetic recording medium, is disclosed. A multilayer film is formed on a shield layer. Unnecessary portions of the multilayer film are removed from both sides of the MR element in a first direction orthogonal to a lamination direction of the multilayer film and parallel to the MR element surface facing the magnetic recording medium. An insulating layer is formed on a surface exposed by removal of the unnecessary portions. An integrated soft magnetic layer covering both sides of the MR element in the first direction and an upper side of the MR element is formed, thereby configuring a second shield layer. An anisotropy application layer is formed on the second shield layer, thereby providing exchange anisotropy to the soft magnetic layer, and magnetizing the soft magnetic layer in a predetermined direction.

摘要： A magnetic head includes a medium facing surface that faces a surface of a recording medium, a write head section, a contact sensor that detects contact of the medium facing surface with the surface of the recording medium, and a heat sink adjacent to the contact sensor. The write head section has a magnetic pole that produces a write magnetic field for writing data on the recording medium. The contact sensor and the heat sink have respective end faces located in the medium facing surface. The contact sensor varies in resistance in response to temperature variations, and is to be energized. The heat sink includes an intermediate layer made of a nonmagnetic metal material, and two ferromagnetic layers made of a metal-based magnetic material, the two ferromagnetic layers being disposed with the intermediate layer therebetween, and being antiferromagnetically exchange-coupled to each other via the intermediate layer.
