Dual AP pinned GMR head with offset layer

摘要

A dual spin valve magnetoresistive structure having a free layer and a spacer layer between the free layer and a pinned layer. The pinned layer is between the spacer layer and the antiferromagnetic layer. There is also an offset layer, where the antiferromagnetic layer is between the offset layer and the pinned layer. The offset layer is tailored to introduce a first magnetic field that reduces a net magnetic field within said free layer.
