A magnetoresistive head (10, 10A) includes a first magnetic shield (16), an antiferromagnetic layer (22, 52) provided on the first magnetic shield (16), a pinned ferromagnetic layer (24) provided on the antiferromagnetic layer (22, 52), a nonmagnetic intermediate layer (26, 66) provided on the pinned ferromagnetic layer (24), and a free ferromagnetic layer (28, 68, 70) provided on the nonmagnetic intermediate layer (26, 66). The magnetoresistive head (10, 10A) further includes a pair of hard magnetic film bias layers (32) provided on the opposite sides of the free ferromagnetic layer (28, 68, 70), a pair of terminal layers (34) provided on the hard magnetic film bias layers (32), a metal oxide film (36, 42) formed on the free ferromagnetic layer (28, 68, 70) at an exposed portion between the pair of terminal layers (34), and a second magnetic shield (40) provided on the pair of terminal layers (34) and the metal oxide film (36, 42). <IMAGE> |
