PROBLEM TO BE SOLVED: To manufacture a magnetic head in which a high precision track width regulating groove is efficiently cut and in which high reliability and improved input/output characteristics are realized. SOLUTION: This method is applied to a magnetic head 1 where metallic magnetic films 5, 6 are formed on the gap-constituting faces of core halves 2, 3 and track width regulating grooves 9, 10 constituting a projected magnetic tape working face 11 corresponding to a recording track width are prepared by cutting/machining on a magnetic tape sliding face 8 by means of a grinding stone 50. In the cutting/machining of the track width regulating grooves 9, 10, the grinding stone 50 is used on which a shaping process is performed on the outer circumferential face 51 after another shaping process is performed on the side face 52.
