A magnetic head having an antiparallel (AP) pinned layer structure with at
least two pinned layers having magnetic moments that are self-pinned
antiparallel to each other. A free layer structure is spaced apart from
the AP pinned layer structure, and includes a first free layer having a
magnetic moment, a second free layer having a magnetic moment pinned
antiparallel to the magnetic moment of the first free layer, and a third
free layer having a magnetic moment pinned antiparallel to the magnetic
moment of the second free layer.
