In a CPP MR disk drive read head, the shield layer has a fixed magnetization oriented substantially parallel to the air-bearing surface (ABS) of the slider that supports the read head. The quiescent magnetization of the sensor free layer is oriented at an angle relative to the magnetization of the shield layer, preferably between 120 and 150 degrees, to optimize the sensor response to magnetic fields from the recorded data bits on the disk. The magnetization of the free layer is biased by a biasing structure that includes a ferromagnetic side biasing layer formed near the side edges of the free layer and a ferromagnetic back biasing layer that is recessed from the ABS and has a magnetization oriented generally orthogonal to the ABS."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Current-perpendicular-to-the-plane (CPP) magnetoresistive (MR) sensor with reference layer integrated in magnetic shield","description":"A current-perpendicular-to-the-plane magnetoresistive (CPP MR) sensor has a shield layers that also functions as the sensor's reference layer.
