ABSTRACT:
A method of manufacturing a magnetic head by bonding a pair of magnetic cores to each other, wherein a residual stress in the magnetic cores upon bonding them together is controlled so that a permeability of the magnetic cores in the vicinity of a magnetic recording medium sliding surface of the magnetic cores may become maximum. Accordingly, the residual stress in the magnetic cores is controlled so that the permeability of the magnetic cores may surely become maximum after forming the magnetic head, thereby ensuring a superior reproduction efficiency of the magnetic head.
