Patent ID: 8107200

Claim:
A grounded, slider mounted CPP GMR or TMR read head protected from noise, cross-talk and electrostatic discharge (ESD) damage comprising: a substrate; a slider mounted magnetic read/write transducer formed on said substrate, said transducer being encapsulated in a dielectric medium and said transducer including a CPP GMR or TMR read head sensor and an inductive write-head having a lower pole adjacent to said read head sensor and there being a protective upper shield and a protective lower shield disposed about said read head sensor wherein said upper shield is between said lower pole and said read head sensor and is separated by said dielectric medium from said lower pole and wherein said lower shield is between said read head sensor and said substrate and is separated from said substrate by said dielectric medium and wherein said read head sensor has conductive leads providing connections for an output thereof to an input of a preamplifier having common-mode rejection circuitry; a resistive/capacitative shunt formed between said read/write transducer and said substrate wherein said shunt includes at least one electrical connection having a low resistance that is less than approximately 100Ω between said substrate and said lower pole, and includes highly resistive connections that are between approximately 1 and 100 kilo Ω between said substrate and said upper shield and between said substrate and said lower shield and further includes balanced capacitances formed between said lower pole and said upper shield, and between said lower shield and said substrate and wherein said substrate is grounded.
