摘要：A magnetoresistive head assembly of the present invention includes amagnetoresistive sensor and an electrostatic discharge and electrical overstressprotection circuit. The magnetoresistive sensor is capable of having conductedtherethrough oppositely-directed first direction current and second direction current.The magnetoresistive sensor is sensitive to first direction currents in excess of a firstpredetermined value and to second direction currents in excess of a second
predetermined value different than the first predetermined value. The electrostaticdischarge and electrical overstress protection circuit is electrically connected to themagnetoresistive sensor for preventing only those first direction currents greater than
the first predetermined value from flowing though the magnetoresistive sensor and onlythose second direction currents greater than the second predetermined value fromflowing through the magnetoresistive sensor.
