Abstract

PURPOSE:To improve the yield of magnetic heads by facilitating the manufacture by forming parallel projections on a magnetic resistance element at right angles to a power supplying direction. CONSTITUTION:A magnetic resistance element 9 is provided with projections 9a in a comb tooth shape at right angles to an easy magnetization axis. The projections 9a increase the amount of magnetic flux passing through an effective stripe width part 9b to improve the performance. Even when the counter surface F of a medium is polished, no influence is exerted upon an effective stripe width W1.
