Abstract

PURPOSE: To easily obtain an optimal gap depth by arranging a conductive contact member at a depth position to be the medium sliding surface of a magnetic head core.
CONSTITUTION: A magnetic head is equipped with a magnetic head core 1 having an erase gap 2 and a read/write gap 3, and sliders 5a and 5b holding the magnetic head core 1 on the both sides, and a grinding work surface 11 over the magnetic head core 1 and the sliders 5a and 5b is ground to the position of the optimal depth of the gaps 2 and 3, and a medium sliding surface 11a is molded in the same way as usual. When the grinding work surface 11 is ground, a conductive contact member 4, which is electrically made contact with a conductive grinder 9 and constitutes a grinding completing time detecting circuit 13, is made independent of the magnetic circuit of the magnetic head, and the grinder having such a member 4 is used at the time of working. In addition, by providing the conductive contact 4 at the position of a maximal depth 6 of the gaps 2 and 3 to be the medium sliding surface 11a of the magnetic head core 1, the grinding is automatically stopped when the optimal gap depth 6 is obtained, and thus the control of the grinding is facilitated.
