ABSTRACT:
In the case where an object to be ground is ground by mounting a horizontally elongated jig onto a grinding head and by bringing the object into contact with a grinding surface of a grinding disk being driven and rotated, the attitude of the grinding head is controlled by an adjust ring that is in surface contact with the grinding surface of the grinding disk while moving the grinding head, the horizontally elongated jig holding thereon the object that has a plurality of thin film magnetic heads arrayed thereon. Thereby, the flatness of the object is improved and variations in the throat heights of many magnetic heads formed on the object to be ground are reduced by allowing the attitude of the object to be controlled with a grinding surface of a grinding disk as a reference.
