A magneto-resistance effect head is provided with a lower conductive layer
which is provided with a recessed portion, and a vertical bias layer is
provided in the recessed portion. A first magnetic layer is provided on
the lower conductive layer. On the first magnetic layer, layered in the
following order are the non-magnetic layer, the fixed layer, the fixing
layer, and the upper layer so as not to be placed immediately above the
vertical bias layer. The non-magnetic layer, the fixed layer, the fixing
layer, and the upper layer are buried in an insulation layer.
Furthermore, an upper conductive layer is provided on the upper layer and
the insulation layer. In the direction of the magnetic field applied by
the vertical bias layer, the free layer is made greater in length than
the fixed layer and the free layer is disposed in proximity to the
vertical bias layer with the distance between the fixed layer and the
vertical bias layer remaining unchanged.
