    摘要: A method for producing a magnetic head, comprising the step of irradiating peripheral parts other than a track portion and/or a slider portion with a laser beam so as to selectively remove surface parts of the irradiated parts, thereby to form the track portion and/or the slider portion. According to this method, the track portion and/or the slider portion of the magnetic head can be worked at high working rate, at high precision and with low working deformation, with the result that the magnetic head of excellent reproduced output and crosstalk characteristics can be readily manufactured.
