Abstract

PURPOSE:To control the depth of a magnetic gap with high accuracy by executing the grinding while measuring an overwrite characteristic by using a magnetic recording medium having a grinding function, and ending the grind, when the overwrite characteristic has become a prescribed value. CONSTITUTION:In a magnetic recording medium having an abrasive material 16, the abrasive material 16 is used for working in the depth direction of a magnetic gap 3, and a signal from the magnetic recording medium can be used for deciding the depth of the magnetic gap 3 related directly to an overwrite characteristic. Accordingly, when the magnetic recording medium having the abrasive material 16 is used, the depth of the magnetic gap 3 can be worked precisely, while measuring the overwrite characteristic. In such a way, a thin film magnetic head whose characteristic is uniform, and also, in which the depth of the magnetic gap 3 has been controlled precisely can be manufactured with high reproducibility.
