ABSTRACT:
Disclosed are methods of allowing the current direction through the sensor or coil of a magneto resistive (MR) read/inductive write head to be consistent with the orienting magnetic field of the sensor or coil by allowing the current direction to be switched by a single mask layer change. This goal is achieved by creating additional connection sites to the non-magnetic mask layer to provide alternative means of connecting element leads to bonding pads and thus providing a choice in which direction to route the current through the sensor or coil of the read/write head.
