Electrostatic discharge protection device for magnetoresistive head

摘要

An electrostatic discharge protection device is disclosed which selectively shunts charge accumulation across electrical conductors emplaced within the device housing. A grounding element is provided on the housing surface which maintains electrical contact with the enclosed electrical conductors so as to form a shorting shunt and place the conductors at substantially similar electrical potentials. The grounding element may be reversibly changed from the operative into an inoperative position to remove the grounding element from electrical contact with the electrical conductors.
