Abstract

PURPOSE:In a thin film magnetic head, to make heat producing in the conductor layer difficult and saturation of thin film magnetic center difficult by keeping the thickness of the second magnetic layer in the gap portion narrower than the gap and also by installing a wear resistance protective layer on top of it.
