    摘要： A differential read head comprises one tri-layer reader or a plurality of tri-layer readers operating in a current perpendicular to plane (CPP) mode. The tri-layer readers each comprise a first free layer, a second free layer, and a nonmagnetic layer positioned therebetween. A nonmagnetic spacer means is positioned between the plurality of tri-layer readers for electrically connecting the plurality of tri-layer readers in series such that a single CPP sense current representing a differential signal flows serially through the read head. With a single tri-layer reader, the free layers are spaced by a width substantially similar to the transition width of the magnetic medium.

    摘要： An apparatus and associated method for a multi-bit memory capable of being selected with a magnetic layer. Various embodiments of the present invention are generally directed to a first selection layer with a low coercivity that is disposed between first and second storage layers that each have a high coercivity. In response to magnetic saturation of the first selection layer, programming of a logical state to the second storage layer is allowed.
