ABSTRACT:
In a slider using thermal expansion type, being adjustable on a flying height thereof, having problems to be solved, i.e., to reduce the electric power consumption, and to lesson the heat load upon a reproducing element thereof, wherein a heating device4is located separating from tip portions of the recording and reproducing elements2and3. Also, for deforming only the vicinity of the heating device4and the recording and reproducing elements2and3, so as to protrude from, the heating device4and the recording and reproducing elements2and3are surrounded by a resin film6of small rigidity, thereby increasing an amount of protrusion of the recording and reproducing elements2and3per a unit of electric power, but without increasing temperature of the reproducing element3, with an aim of the structure of cutting off the force from materials of circumferences against the deformation.
