Abstract
A magnetic head 1 provided with head chips 3 at distal end portions 2a of base plates 2. A punch 12 is abutted against each of the base plates 2 which is placed on a die 11, and a shearing force is applied to the base plate to plastically deform the distal end portion 2a, whereby adjustment of the height can be conducted while the sliding face of the head chip is kept in parallel to a reference track plane.
Claims4
A method of adjusting a height of a head chip, which is attached to one end portion of a base plate to constitute a magnetic head, with respect to a reference plane of the base plate, comprising the steps of:
- placing a face of the base plate which is to be the reference plane onto a first plane face of a die member;
- and
- punching a punch member onto a predetermined portion of the base plate toward a diagonal direction with respect to the reference plane such that a portion of the base member on which the head chip is attached is shearing-deformed by a predetermined amount in the punching direction.
