ABSTRACT:
The invention allows a thin-film magnetic head that meets specifications required by the customer to be provided in a short period of time and manufacturing costs to be reduced. A slider includes a first surface and a second surface each facing opposite directions. Two magnetic head element portions are formed in the slider near an end face orthogonal to the direction of air flow. One of the element portions is placed to face the first surface. The other element portion is placed to face the second surface. The element portions are placed in symmetrical positions with respect to a place parallel to the first and second surfaces. On the end face four pad-shaped electrodes are provided for electrically connecting the two element portions to an external device. The electrodes are selectively connected to any of the element portions through four conductors.
