Patent ID: 7392579

Claim:
A method for protecting a slider mounted CPP GMR or TMR read head sensor from noise, cross-talk and electrostatic discharge (ESD) damage comprising: providing a grounded, slider mounted magnetic read/write transducer, said transducer being encapsulated in an dielectric medium and said transducer including the CPP GMR or TMR read head sensor, an inductive write head having a lower pole adjacent to said sensor and protective upper and lower shields disposed about the sensor and said sensor having conducting leads providing connections for an output thereof; forming a resistive/capacitative shunt between said read head sensor and a substrate wherein said shunt includes at least one electrical connection between the substrate and the pole, the upper shield and the lower shield and further includes balanced capacitances formed between the pole and the upper shield, the upper shield and the lower shield and the lower shield and the substrate; connecting the output of said read head sensor to an input of a read-back preamplifier, said read-back preamplifier employing common mode rejection circuitry.
