Abstract: Tolerances for manufacturing reader structures for transducer heads continue to grow smaller and storage density in corresponding storage media increases. Reader stop layers may be utilized during manufacturing of reader structures to protect various layers of the reader structure from recession and/or scratches while processing other non-protected layers of the reader structure. For example, the stop layer may have a very low polish rate during mechanical or chemical-mechanical polishing. Surrounding areas may be significantly polished while a structure protected by a stop layer with a very low polish rate is substantially unaffected. The stop layer may then be removed via etching, for example, after the mechanical or chemical-mechanical polishing is completed.

Abstract: The implementations disclosed herein provide for a spin transport sensor including a synthetic antiferromagnet (SAF) adjacent a shield element. The SAF extends to an air-bearing surface (ABS) and provides a current path from a current source to an ABS-region of a spin conductor layer. Spin current diffuses from the spin conductor layer to an adjacent free layer, which generates a measurable electrical voltage in a free layer of the spin transport sensor. The SAF serves as both a magnetic shield and a spin injector to the spin conductor layer.
