  • TMR head structure with conductive shunt
    Patent number: 7151654
    Abstract: The sensor of the present invention is a tunneling magnetoresistive read sensor that includes first and second electrodes, and a stack positioned between the electrodes. The stack includes at least one sense layer and a tunnel barrier. A shunt member is operatively coupled to the electrodes in parallel with the stack. The shunt member diverts current flowing from the first electrode to the second electrode when the sensor is operational so that current simultaneously flows through the stack and the shunt member to reduce the effective resistance of the sensor.
