ABSTRACT:
A magnetoresistance element is arranged in a plane parallel to the end face of a PG yoke and is situated on the outer side of a circle described by revolution of the PG yoke end face and in close proximity to the end face to detect a characteristic flux component emitted from the PG yoke end face. The magnetoresistance element is disposed in such a manner that an acute angle is formed between the direction of a current flowing in the element and a normal line extending from the axis of rotation of a recording medium. A flux component hardly influenced by the area of the PG yoke end face is thus detected.
