Large parasitic resistance from the antiferromagnetic pinning layers lower the magnetoresistance for the CPP GMR sensor. We disclose a structure to lower the parasitic resistance. The pinning layers, the antiferromagnetic layers, and portions of the ferromagnetic pinned layers are extended in the track width and stripe height direction to decrease the resistance contribution from these layers. The calculation shows 20% reduction in parasitic resistance for this structure.
