摘要： Since structural portions of a device made of a plurality of materials are different from one another in mechanical hardness, it is very difficult to uniformly lap the structural portions. This is attributable to generation of machining recessions due to differences in lapped amount when large fixed abrasive grains are used, and generation of lapping marks caused by that the dropped abrasive grains rotate. Accordingly, in order to cope with the disadvantage, it is essential to surely grip abrasive grains of small size to a surface of a surface plate.[Solving Means]Abrasive grains are fixedly forced into a surface of a lapping tool with mechanical pressure and then the surface of the lapping tool including the abrasive grains is subjected to plasma processing, whereby an improvement in adhesion between the abrasive grains and a surface plate and reduction in the number of loose abrasive grains, which are dropped from the surface of the lapping tool, can be achieved, so that it is possible to realize lapping, in which a surface of a device made of a plurality of materials is made very plane.

摘要： A magnetic head slider having an air bearing surface overcoat that has excellent corrosion resistance and wear resistance despite its very small thickness is provided. In one embodiment, a method of producing a magnetic head slider comprises the steps of forming, on the air bearing surface of the slider, an air bearing surface overcoat which is a film stack of an amorphous silicon film and a hard amorphous carbon film, removing the surface region from the hard amorphous carbon film by the irradiation with an ion beam which is tilted with respect to a normal to the air bearing surface, and forming a rail in the air bearing surface on which the air bearing surface overcoat has been formed. The amount of the diamond component in the hard amorphous carbon film must not be smaller than about 45% and, desirably, in a range of about 60% to 85%. A high density and covering performance are obtained when the angle of irradiating the ion beam is not smaller than about 60 degrees from a normal to the air bearing surface of the magnetic head slider and when the acceleration voltage for the ion beam is not higher than about 300 V in the step of removing part of the air bearing surface overcoat.

A mask having an arbitrary pattern shape provided for forming the track guide separation area in the magnetic film is formed on the magnetic film, and the track guide separation area is formed by irradiating ions and electrons onto the surface of the magnetic film and applying an intermittent voltage to the substrate, thereby non-magnetizing the area irradiated.

摘要： A magnetic head suitable for high-density recording is provided at a high yield by a method that suppresses a reduction in reproducing output signal due to ion-beam irradiation. After an air-bearing surface of a read element, a magnetic-head element, or a row bar is mechanically polished, the air-bearing surface is irradiated with an ion beam, such that an orthographic projection of an ion-beam incidence direction onto the air-bearing surface forms an in-plane incidence angle of 30 degrees to 150 degrees or of 210 degrees to 330 degrees with respect to a track-width direction. Thereby, the formation of a short circuit due to ion-beam irradiation may be hindered.
