ABSTRACT:
A magneto-resistance effect type magnetic head incorporates a grounded conductive layer, a second thin film magnetic core and an MR sensing part, the conductive layer being located near the thin film magnetic core, the layer and the core being electrically connected. The conductive layer is further connected electrically to an electrode of the MR sensing part, the electrode facing an air bearing surface. This setup protects the MR sensing part from static electricity destruction, thus providing a magneto-resistance effect type magnetic head of high reliability.
