摘要： A method of producing a thin film magnetic head includes the steps of: forming a second lower magnetic pole layer in a part on a first lower magnetic pole layer; forming, over the entire wafer surface, an insulating layer so as to be thicker than the thickness of the second lower magnetic pole layer in the stacking direction, the insulating layer being less likely to be etched than the second lower magnetic pole layer; carrying out a planarizing process by CMP on the entire wafer surface until the second lower magnetic pole layer is exposed; forming a concave portion including the second lower magnetic pole layer and the insulating layer by ion beam etching on the entire wafer surface; forming a recording gap layer over the entire wafer surface; and forming a first upper magnetic pole layer in the upper magnetic pole layer so as to fill the concave portion.

摘要： A thin-film magnetic head that has an improved protrusion efficiency under the condition of not only assuring the reliability of the-heating operation, but also stabilizing the read output is provided. The head comprises: a magnetic head element for writing and/or reading data signals; a heating element for generating heat at least during operations of the magnetic head element; and a first heatsink element provided adjacent to the heating element for receiving a part of the heat generated from the heating element, the first heatsink element being a distance from the magnetic head element.
