Abstract

PURPOSE:To reduce a force, which is required for deforming elastically a conductive stylus, and the stylus pressure, by constituting the conductive stylus with an elastic material. CONSTITUTION:A conductive stylus 2 is mounted at the tip of a supporting arm 3 consisting of an insulating substance, and the supporting arm 3 is fixed to the tip of a metallic cantilever 4. This conductive stylus 2 is formed with an elastic narrow metallic wire with 1-3mm. length, and the section is square tapers off. Thus, the conductive stylus 2 follows up the vertical vibration of a recording medium 1 to deform elastically, and the tip is always brought into contact with the surface of the recording medium 1 well to make the signal reproducing due to the detection of an electrostatic capacity possible, and the occurrence of the noise due to static electricity generated by friction between the stylus and the recording medium is reduced.
