Abstract:
A reader sensor having a composite shield and a sensor stack. The composite shield includes a high magnetic moment layer having a magnetic moment greater than 1.0 T, a low magnetic moment layer, and a spacer therebetween. The high magnetic moment layer is closer to the stack than the low magnetic moment layer. The high magnetic moment layer may be a single layer or have a plurality of layers.
