摘要：
In a thin film magnetic head consisting of a non-magnetic substrate, and a multilayer structure superposed thereon and including a lower core, a gap material layer, a thin film coil and an upper core, etc., the head sliding surface of the lower core and that of the upper core are so formed that they become wider with increasing distance from the surface of the gap material layer.
