Abstract
A multi-gap head apparatus employed in a measuring system using a magnetic scale. First and second thin plates, making up core members, are stamped out with a selected width near the center portion of alternately stacked first rolled plates and second rolled plates made of a highly permeable material and a non-magnetic material, respectively. A compensator plate is interposed between the core members in order to compensate for output distortion due to a thickness error of the first and second thin plates.
