Patent ID: 7724477

Claim:
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: temporarily mounting the floating-type magnetic head device with respect to a rotating disk equivalent surface so as to float the head body; measuring a roll-angle corresponding amount at the end of the load beam; and correcting the floating-type magnetic head device on the basis of the roll-angle corresponding amount at the end of the load beam by bending the load beam in a direction such that a roll angle of the head body with respect to the rotating disk equivalent surface is minimized, wherein bending the load beam is performed: along a line inclined to a direction perpendicular to the longitudinal direction of the load beam; at a position of the load beam closer to a swinging fulcrum of the load beam than to a connection point between the load beam and the flexure; and by irradiating on the inclined line on the load beam with a laser beam, 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.
