PROBLEM TO BE SOLVED: To provide a reader sensor stack.SOLUTION: A reader sensor has a sensor stack. The reader sensor stack includes an AFM layer, a pinned stabilization layer, and a pinned layer, with the pinned stabilization layer closer to the AFM layer than to the pinned layer. The reader sensor stack also includes a non-magnetic spacer layer between and in contact with the pinned stabilization layer and the pinned layer. A magnetic coupling between the pinned stabilization layer and the pinned layer is 50% or less of a magnetic coupling between the pinned stabilization layer and the AFM layer.SELECTED DRAWING: Figure 1 |
