ABSTRACT:
The yoke thin film magnetic head according to the present invention includes yokes for leading the magnetic flux of signals generated from the magnetic recording medium up to the magnetic resistance effect element, which yokes are made of sputtered films having compressive stress therein. Therefore, the internal stress in the yokes which cause bad influences upon magnetic properties of the magnetic resistance effect element can be negated or reduced, with less Barkhausen noises produced.
