Abstract
A magnetoresistive effect type magnetic head has a magnetoresistive effect (magnetoresistive effect film) and a soft adjacent layer (SAL) that is disposed in opposition to the magnetoresistive effect film via an intervening non-magnetic film, for the purpose of applying a transversal bias magnetic field to the magnetoresistive effect film, and also has an antiferromagnetic film which is disposed so as to be in contact with at least part of the magnetoresistive effect film, for the purpose of applying a longitudinal bias magnetic field to the magnetoresistive effect film. The surface area of the region over which the magnetoresistive effect film makes contact with the antiferromagnetic film is established so as to be greater than the surface area of the active region thereof which does not contact the antiferromagnetic film.
