A method for setting a voltage (Vsub) of a substrate to about a voltage (Vshield) of a shield of at least one reader formed above the substrate is presented in one embodiment. The method includes passing an MR bias current through each MR sensor of at least one reader formed above a substrate; and setting a voltage (Vsub) of the substrate to about the voltage (Vshield) of a shield of the at least one reader. A method according to another embodiment includes passing a bias current through at least one reader formed above a substrate, the at least one reader further comprising a shield and a magnetoresistive (MR) sensor, the substrate being at about a voltage (Vsub); and operatively adjusting a voltage (Vshield) of the shield of the at least one reader to about match the Vsub. Additional methods are also presented.
