ABSTRACT:
In a lead overlay (LOL) type of read head first and second insulation layers are employed with the first insulation layer being located between a top surface of a first hard bias layer and a first lead layer and the second insulation layer is located between the top surface of a second hard bias layer and a second lead layer for minimizing a shunting of a sense current through the hard bias layers into a read sensor.
