Abstract
A magnetic transducer head utilizing a thin film magneto-resistance effect element is disclosed in which the amount of a DC bias magnetic field is so selected that only the end portion of the thin film magneto-resistance effect element serving as a contact surface with a magnetic medium is effectively given with sensitivity and the element is saturated in the vicinity of its central portion in its width direction.
