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.

Abstract: A magnetic recording head includes a plurality of writers and at least one reader. The plurality of writers and the reader define a plurality of close points of the head. The plurality of writers are spaced apart from one another in a cross-track direction and positioned in the same plane of the head. A plurality of contact sensors are positioned proximate the plurality of writers and the reader. The contact sensors are coupled together and to a pair of electrical bond pads of the head and configured to sense for head-disk contact at each of the close points.
