Abstract

PURPOSE:To achieve the improvement in the characteristics of magnetic heads and achieve the improvement in yield by beforehand providing a groove having an opening in the position where the depth to impedance at the operating gap forming face to be removed later has a correlation and using this as a measure at the time of depth fabricating of the magnetic head.
