Abstract
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.
Claims5
A method for producing a magnetic head comprising the steps of irradiating peripheral parts other than a track portion of a magnetic head core with a laser beam so as to selectively remove a portion of the surface of the irradiated parts, thereby to form said track portion including passing said laser beam through a slit having a predetermined pattern to shape said beam and then focusing the shaped beam onto said magnetic head core to thereby irradiate said peripheral parts with said laser beam.
