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 free layer is provided on the lower
conductive layer. On the free 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.
