Abstract
In one embodiment of the present invention, 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, removing the surface region from a 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. 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.
