Abstract

PURPOSE:To manufacture a magnetic head which is large in bonding strength and excellent in gap accuracy, by providing a notched part and an alloy bonded layer between the lower end of a front gap of a magnetic head core, and the winding window. CONSTITUTION:To the inside surface 16 of a front gap side of a winding groove 12 provided on one surface of a sendast wafer 11 made of an alloy magnetic material, and the inside of a bonding material filling groove 13, bonding materials 14, 15 are made to stick so as to be heaped up from one surface of wafer 11, and after that, a groove 17 is provided on the front gap side of the winding groove 12. Subsequently, the inside of this groove 17 is filled with a heat-resisting inorganic adhesive agent 18, and after is has become dry, the adhesive agent 18 is solidified by means of heat treatment. Subsequently, one surface of this wafer 11 is polished to a mirror surface, and after that, it is butted with the other wafer 19, is heated up to a temperature of a melting point of higher of the bonding materials 14, 15, the wafers are made to adhere so as to be unified, are brought to slicing, and the processing for prescribed thickness and the surface processing for contacting with a tape are executed.
