摘要

PROBLEM TO BE SOLVED: To suppress variation by controlling throat height in the integration process of a thin film magnetic head. SOLUTION: The method for manufacturing the thin film magnetic head comprises processes of: forming an MR (Magneto-resistive) element; a process for forming a 1st yoke part layer; forming a non-magnetic layer 8c for specifying the throat height TH on a part of the 1st yoke part layer; and forming a 1st magnetic pole part layer for constituting a 1st magnetic pole layer, a recording gap layer, and a 2nd magnetic pole part layer for constituting a 2nd magnetic pole layer for recording data in a recording medium on the upper surface of the 1st yoke part layer and the non-magnetic layer. The position THO of the non-magnetic layer end part that is the end part of a medium counter face ABS side of the non-magnetic layer 8c is set by the position of the MR element end part MRHO that is the opposite side end part of the medium counter face ABS of the MR element, and an end part distance Z that is the distance from the MR element up to the non-magnetic layer end part.
