    Abstract: The implementations disclosed herein allow for formation of a magnetoresistive (MR) sensor shield that shields against both down track and cross-track interference. The shield can be formed in a single deposition step. In one implementation of the disclosed technology, a “tail” portion of the shield is eliminated by including a non-magnetic material adjacent to opposite sides of a middle portion of the sensor stack.

    Abstract: A magneto-resistive (MR) sensor may include a variety of individual functional layers whereby an electrical resistance throughout the layers of the sensor stack varies according to the polarity of a pinned layer within the sensor stack. A layered synthetic anti-ferromagnetic (SAF) upper shield of the MR sensor includes an upper SAF layer and a lower SAF layer separated by a shield anti-ferromagnetic (AFM) layer. The lower SAF layer is in contact with a side shield of the MR sensor, which provides a side shield biasing field to the MR sensor. The upper SAF layer separates the lower SAF layer from a top shield and/or domain control structure (DCS) magnet(s) of the MR sensor and shields the lower SAF layer and the sensor stack from DCS stray field(s), thereby reducing noise.
