Abstract

PURPOSE:To ensure an easy fine adjustment for a bias magnetic field to increase the rate of nondefective products, by distributing a soft magnetic material near a magnetic reluctance effect element and applying the magnetic field to the soft magnetic material with a magnet or an elecromagnet. CONSTITUTION:A bias magnetic field soft magnetic material 4 is distributed adjacently to a magnetic reluctance effect (MR) element 1, and the material 4 is extended to the upper and lower parts of a head. Then a yoke 5 is added to form a magnetic circuit by means of a permanent magnet or an electromagnet wound with a coil 6. If the material 4 is divided into sections at the positions of MR elements 1 (figure c), the efficiency is increased to facilitate an easy fine adjustment of a bias magnetic field. As a result, the rate of nondefective products is increased.
