Abstract

The contour effect of a magnetic head was analyzed using a finite element method, and a new type of head with a reduced contour effect was fabricated on the basis of the simulation described in this paper. Few studies of the contour effect of the magnetic head have used the finite element method. The core shape and the position of the shielding case were simulated to improve the contour effect. The following results were obtained: (1) the level in the contour effect depends mainly on both 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 fabricated with a contour effect of less than 5 dB in the frequency range from 20 to 50 Hz
