ABSTRACT:
In a magnetoresistive effect head comprising a ferromagnetic magnetoresistive effect layer, an inverse ferromagnetic layer (3) for generating a longitudinal bias magnetic field by an exchange force with respect to the ferromagnetic magnetoresistive effect layer (4), a ground layer (2) having a face-centered cubic structure is provided on only a portion of the anti-ferromagnetic layer. In the magnetoresistive effect head further comprising a soft magnetic bias-assistant layer (12) for a transversal bias magnetic field in the ferromagnetic magnetoresistive effect layer (15), the soft magnetic bias-assistant layer (12) has a crystal structure other than a face-centered cubic structure, the ground layer (13) having a face-centered cubic structure is provided on only a portion of the anti-ferromagnetic layer (14).
