Abstract
Both of decreasing the direct current resistance and flattening of the top face of the element can be simultaneously attained by forming a first lead layer under the bottom side of a laminated body as well as by reducing the film thickness of a second lead layer located at both sides of the laminated body. Excessive signals from outside of the area of the track width Tw are not picked up during regeneration operation since the width of the laminated body is adjusted to be nearly equal to the track width Tw thereby enabling to attain a good regenerative characteristic.
