The series resistance of a CPP read head having in-stack biasing has been
reduced by stitching the AFM layer through a high conductance layer. Both
the AFM and high conductance layers have significantly larger
cross-sectional areas than the high conductance layer of prior art
structures so the contribution, to the total resistance of the device,
from the AFM layer as well as from spreading resistance at the stack-lead
interface, is significantly reduced. The high conductance layer provides
sufficient ferromagnetic coupling to enable the AFM to stabilize the
in-stack bias layer. A process to manufacture the device is also
described.
