| 摘要 |
A magnetoresistive head has a spin valve effect element constituted by sequentially laminating at least a first thin film layer of magnetic material (23), a thin film layer of non-magnetic material (24), a second thin film layer of magnetic material (25) and a thin film layer of antiferromagnetic material (26) on a substrate (21). The first thin film layer of magnetic material (23) is formed only in a central active region corresponding to a track width (WT) of the head. <IMAGE> |
