Abstract
The method of manufacturing a magnetic head comprises the steps of: forming a plurality of layers, which are made from prescribed materials, on a substrate; and forming a plurality of magnetic head elements on the substrate. Using a first ELG element whose size in a prescribed direction is bigger than that of the magnetic head elements and a second ELG element whose size is equal to that of the magnetic head elements, on the substrate, a work piece is lapped, while monitoring resistance of the first ELG element when the resistance of the first ELG element reaches a prescribed value, the amount of lapping the work piece is adjusted on the basis of resistance of the second ELG element Thus, a bar-shaped member can be precisely lapped, the magnetic heads can be manufactured without scattering their characteristics, and yield rate of manufacturing can be improved.
