ABSTRACT:
In a yoke type reproducing magnetic head, a magnetoresistance effect film can be arranged in the vicinity of a medium facing surface, so that sensitivity is improved. The yoke type reproducing magnetic head comprises: a pair of magnetic yokes which face each other via a magnetic gap, at least one of the pair of magnetic yokes extending from a medium facing surface to a position retracted from the medium facing surface; a magnetoresistance effect film which has a curved portion protruding toward the medium facing surface in the magnetic gap and which is magnetically connected to the magnetic yokes; and an electrode which is electrically connected to the magnetoresistance effect film.
