Magnetic head producing method

摘要

A method of producing a magnetic head comprising the steps of forming a track width restricting groove on each of a pair of head core blocks (91); fusion joining the head core blocks (91) to each other with glass while the head core blocks (91) are positioned with the track width resticting grooves aligned with each other; forming, on at least one of a pair of faces of the head core blocks (91) remote from joining faces at which the head core blocks (91) are joined to each other, a groove at an angle substantially equal to an azimuth angle of a magnetic gap of a magnetic head to be produced; and cutting the head core blocks (91) in a direction substantially perpendicular to a bottom face of the groove to form a head chip. <IMAGE>
