PURPOSE:To chamfering work all the ridge line parts of a magnetic head by the chamfering work in one time by installing an elastic body in flat plate shape onto a tape guide surface and installing a pressing device for pressing a magnetic head during the shift onto the polishing tape which contacts the surface of the elastic body. CONSTITUTION:When a test piece board 9 is shifted leftward by a shifting device, a roller 8 contacts the inclined surface 11a of the pressing cam 11 of a pressing device, and the test piece board 9 is raised, and a magnetic head 10 is pressed onto a polishing tape 1 by the force of the weight 12 of a pressing device. When the test piece board 9 is shifted in a desired direction by the shifting device, an elastic body 7 is deformed, and the polishing tape 1 deforms in accordance with the unevenness of the magnetic head 10. Therefore, only the outer ridge line part 10b and the inner ridge line part 10c of the magnetic head 10 contact the polishing tape 1, and chamfering work is carried out. |
