Reader sensor structure having front bottom shield adjacent recessed AFM layer

摘要

A sensor structure that has a sensor stack comprising a recessed AFM layer, a combined pinned layer/reference layer (PL/RL) directly on the AFM layer, a free layer (FL), and a barrier layer between the PL/RL and the FL. All the magnetic layers between the AFM layer and the FL have substantially the same magnetic orientation. The sensor structure includes a top shield and a front bottom shield adjacent to the recessed AFM layer.
