Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a magnetic head device for improving positioning and bonding precision to the elastic supporting member of a head slider and the magnetic head device. SOLUTION: This method for manufacturing a magnetic head comprises a head slider mounting process for mounting a head slider 11 equipped with a magnetic head element for recording and/or reproducing information for a medium on a mounting part 12a of an elastic supporting member 12. This method also comprises a mounting part reference position detecting process for detecting the reference position of the mounting part of the elastic supporting member, a head slider reference position detecting process for detecting the reference position based on the shape of one part of the head slider, an integrating process for integrating the relative positions of the reference positions of the mounting part of the elastic supporting member and the head slider which are respectively detected by the mounting part reference position detecting process and the head slider reference position detecting process, and a bonding process for mutually bonding the elastic supporting member and the head slider.

Abstract: PROBLEM TO BE SOLVED: To improve overlay accuracy, by executing edge detection based on a center of a pattern constituting a vernier, and measuring a deviation amount of overlapping verniers by a central value between obtained vernier edges. SOLUTION: A paired edge (an edge regarding one vernier pattern) is searched relating edge detection windows 12, 12' to a scale of a detected vernier. The edge detection window 12 carries out the search as for upper verniers 1 to 11 and the edge detection window 12' carries a search as for lower verniers 1' to 11'. A deviation amount of upper and lower vernier patterns is given by a distance between a central point of a measured upper vernier pattern and a central point of a measured lower vernier pattern. In an edge detection window, an edge is taken in a direction from the verniers 1 to the vernier 11, calculation is carried out one by on between verniers 1 and 1', 2 and 2',..., 11 and 11', and the scale of a smallest value of difference in calculation result is a deviation amount of the vernier.

Abstract: PROBLEM TO BE SOLVED: To provide a head slider assembling method and a magnetic head device, capable of facilitating the sure electric grounding of a head slider to an elastic supporting member, and performing the easy verification of the grounding by a conductive material. SOLUTION: This magnetic head manufacturing method comprises a head slider attaching process for attachment to a head slider 11 provided with a magnetic head element for recording and/or reproducing information in a medium. The head slider attaching process includes the adhesive coating step of coating adhesive 20 to the adhesive part of the attaching part of the head slider and/or an elastic supporting member, the conductive material coating step of coating conductive materials 21 and 21a, and the adhering step of adhering these, and in the conductive material coating step, the conductive materials are coated so as to protrude out from the adhesive parts by proper amounts after the adhering step.
