A magnetoresistive head for detecting a magnetic signal on a recording medium as a reproduction signal includes a first magnetic shield, a first electrode terminal disposed on the first magnetic shield, a magnetoresistive film disposed on the first electrode terminal, magnetic domain control films disposed on both sides of the magnetoresistive film for controlling magnetic domains in the magnetoresistive film by applying a bias magnetic field in a first direction to the magnetoresistive film. The magnetoresistive head further includes a second electrode terminal disposed on the magnetoresistive film, and a second magnetic shield disposed on the second electrode terminal. At the time of reproduction of the magnetic signal, a sense current is passed across the first and second electrode terminals in the direction perpendicular to the film plane of the magnetoresistive film so that the direction of a current magnetic field in a medium-opposed end portion of the magnetoresistive film is in the first direction.
