1. A glide head comprising:

  • a glide body including a leading edge, a trailing edge and a contoured surface having a raised bearing surface elevated from a recessed bearing surface;

    at least one thermal transducer fabricated on the raised bearing surface having a surface portion extending along the raised bearing surface to form a glide interface to detect asperities and the at least one thermal transducer being in electrical contact with an electrically conductive pad proximate to the trailing edge of the glide body; and

    a conductive strip conductively coupled to the at least one thermal transducer and the conductive pad to provide an electrical contact between the at least one thermal transducer and the conductive pad.
