Abstract
A method for manufacturing a magnetic transducer head in which a track width regulating grooves provided on both edges of a magnetic gap are filled by blowing a powder beam of nonmagnetic material having a very fine particle size to deposit the nonmagnetic material in the grooves. A pair of magnetic core members are bonded together to form a magnetic gap therebetween by providing a metal layer of a bonding surface of the core members and applying a pressure to the core members under an elevated temperature to cause a mutual diffusion of the metal to bond the core members together. Thus the magnetic transducer head can be made without using a high-temperature heat treatment.
