Abstract:
A magnetic head polishing apparatus for polishing a polished work bearing a plurality of magnetic heads, comprising a rotated polishing table having a polishing plane constituting a part of a spherical plane of a predetermined radius of curvature; a polishing head mounting frame provided movably with respect to said polishing plane; and a polishing head supported by said polishing head mounting frame;wherein said polishing head includes a jig for supporting said polished work through an elastic member; a back plate on which said jig is mounted; an elevator unit capable of ascending and descending integrally with said back plate with respect to said polishing plane and supporting said back plate in rotatable manner about a supporting point and in a plane parallel to the direction of said ascent and descent; plural correcting actuator means for pressing said back plate to said polishing plane; measuring means for measuring a property of the magnetic head formed on said polished work; and control means for controlling the pressing forces of said plural correcting actuator means according to thus measured value.
