Patent ID: 7359152

Claim:
A thin film magnetic head structure comprising, on one of surfaces of a substrate: a plurality of thin film magnetic head precursors each including both of a reproducing head portion and a recording head portion, as precursors to become a plurality of thin film magnetic heads each including both of the reproducing head portion and the recording head portion and having a recording-medium-facing surface which faces a recoding medium; a plurality of first resistance film patterns used to control progress of a polishing process on the reproducing head portion at the time of forming the thin film magnetic head by forming the recording-medium-facing surface by polishing the substrate together with the thin film magnetic head precursor; and a plurality of second resistance film patterns used to control progress of a polishing process on the recording head portion at the time of forming the thin film magnetic head by forming the recording-medium-facing surface by polishing the substrate together with the thin film magnetic head precursor.
