Abstract: 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.

Abstract: The head slider has a plurality of heaters each heating a corresponding region of the ABS, and a sensor detecting collision of the ABS with a projection on a surface of the magnetic disk. Currents supplied to the respective heaters are controlled and produce heats independently of one another. The heats produce projections on the corresponding regions of the ABS, respectively. The ABS with asperity can be planarized through appropriately controlling magnitude of the currents supplied to the heaters. Thus, the variation of a sensor output depending on asperity of the ABS is effectively reduced. Another head slider has a heater locally heating a corresponding region of the ABS. The heater has a structure where a central portion is away from the ABS compared with end portions, or a structure where calorific power of a central portion is smaller than that of each of end portions. Thus, overall projection shape becomes flat.

Abstract: A heater member is formed in structure including a heater layer with a low electrical resistivity and a cap layer with a higher electrical resistivity, an electrically conductive electrode film is formed thereon, and electrically conductive bumps are formed thereon by plating. Unnecessary part of the electrode film is removed using the bumps as a mask. The heater member generates heat to thermally expand a thin-film magnetic head, whereby the distance is reduced between a recording medium and, a magnetoresistive device and/or an electromagnetic conversion device. During removal of the electrode film part of the cap layer with the higher electrical resistivity in the heater member is removed together with the electrode film, which reduces the variation in the total resistance of the heater member.
