Abstract

PURPOSE:To grind the end face of a thin film magnetic head formed on a glass substrate with high precision and prevent a grinding surface from being broken by uniformly clamping a ground body holder on a grinding material and linearly reciprocating it in the grinding direction. CONSTITUTION:A ground body 6 is clamped under proper pressure on a lapping material 8 by a forcing means 9, and a holder 5 is linearly reciprocated by alternately actuating drive sections 13 and 14. This permits the ground body 6 to be ground following the grinding of a reference body 7. In this case, since the reference body 7 is provided at all the regions in the lengthwise direction on the grinding surface of the holder 5, the pressure under which the ground body 6 is clamped on the lapping material 8 is kept constantly and uniformly. As a result, high precision grinding is enabled and the breaking and cracking on the grinding surface can be prevented.
