Abstract:
1. A correcting method for a floating-type magnetic head device for use with a recording medium, the floating-type magnetic head device comprising: a load beam made of a metallic material; a flexure, having an elastically flexible tongue piece located on the load beam adjacent to the recording medium, made of a metallic material and connected to the load beam; and a head body fixed on the surface of the tongue piece, adjacent to the recording medium, wherein during rotation of the recording medium, the head body floats over the recording medium, the correcting method comprising: wherein bending the load beam is performed: wherein the roll-angle corresponding amount is estimated by heights of two points spaced from each other in the track width direction of the load beam, and wherein the direction of the inclined line and the intensity of the laser beam are determined on the basis of the roll-angle corresponding amount.
