Abstract
A thin-film magnetic head that shows stable read and/or write performances, maintaining the reliability over time by suppressing the wear of the head sufficiently, is provided. The head comprises: a substrate having an element-formed surface and an opposed-to-medium surface; a magnetic head element; an overcoat layer formed on the element-formed surface so as to cover the magnetic head element; a closure provided on the overcoat layer, a surface of the closure being in contact with the upper surface of the overcoat layer; and an element contact pad formed in a sliding-side surface of the head and having a contact surface including a part of the opposed-to-medium surface, a part of an end surface of the overcoat layer and a part of an end surface of the closure, one end of the magnetic head element reaching the contact surface.
