Abstract
A contact sensor is provided at or near an air bearing surface of a slider and having a temperature coefficient of resistance. The contact sensor is coupled to a lead arrangement comprising a first lead and a second lead. The contact sensor comprises a sensor element, a first peripheral wing comprising an inner wing connected to the sensor element and an outer wing connected to the first lead, and a second peripheral wing comprising an inner wing connected to the sensor element and an outer wing connected to the second lead. An electrically conductive overlay covers at least the outer wings of the first and second peripheral wings and some or all of the first and second electrical leads.
