Abstract:
A magnetic head for reproducing a signal recorded on a recording medium, comprising:a substrate; a magnetic head core provided on the substrate, having a magnetic gap; and a first magnetoresistance device provided an the magnetic head core, wherein the first magnetoresistance device comprises: a first insulating layer provided on the magnetic head core; and a first pinned layer provided on a side of the first insulating layer opposite to the magnetic head core, wherein a magnetization direction is not easily rotated in the first pinned layer, wherein the magnetic head core comprises a first soft magnetic layer provided at a position corresponding to the first insulating layer, and the first soft magnetic layer functions as a first free layer of the first magnetoresistance device, wherein a magnetization direction is easily rotated in the first free layer.
