SIMULATION OF CONTOUR EFFECT ON MAGNETIC HEAD

The contour effect of a magnetic head was analyzed using a finite elem ent method, and a new type of head with a reduced contour effect was f abricated on the basis of the simulation described in this paper. Few studies of the contour effect of the magnetic head have used the finit e element method. The core shape and the position of the shielding cas e were simulated to improve the contour effect. The following results were obtained; (1) the level in the contour effect depends mainly on b oth the position and the size of the shielding case, (2) the phase of the contour effect depends on the core shape and (3) a new head was fa bricated with a contour effect of less than 5 dB in the frequency rang e from 20 to 50 Hz.
