Current perpendicular to plane type magnetoresistive device, magnetic head, and magnetic recording/reproducing apparatus

A current perpendicular to plane type magnetoresistive device comprising:

• a magnetoresistive film;
• a pair of electrodes which allow a sense current to flow through the magnetoresistive film in a perpendicular direction to a film plane;
• a biasing film which imparts a biasing magnetic field to the magnetoresistive film in a parallel direction to the film plane;
• and
• a magnetic film disposed in a vicinity of an air-bearing surface of the magnetoresistive film where a signal magnetic flux is introduced to the magnetic film;
• wherein the direction of the magnetic field generated by the sense current flowing through the magnetoresistive film in the perpendicular direction to the film plane is made substantially anti-parallel to the direction of the biasing magnetic field in the magnetic film disposed in the vicinity of the air-bearing surface.
