ABSTRACT:
A thin film magnetic head has a layer of soft magnetic material formed on a substrate. The layer is formed into two yoke pieces and a magnetic return path, which form a gap at ends of the yoke pieces. The opposite ends of the yoke pieces are joined to the magnetic return path by overlaying magneto-resistive pieces to which an electrical bias is applied.
