Abstract

PURPOSE:To achieve easy forming of a minute tip and to increase a fitting angle accuracy with a cunti-lever, by processing the tip after forming an electrode layer on a plane split longitudinally into two for a reproducing stylus member. CONSTITUTION:One side plane 22 of a reproducing stylus main body 20 is taken as a flat plane, a slope 24 over the plane 22 and a scanning slide plane 23 is formed at a track sliding tip, and a projection 25 having a convex cross section toward lengthwise direction of the main body is left at the center of the slope. This projection 25 is taken as a width W possible for the detection of change in static capacitance with information bits, one side 26 is taken as an incorporated plane as the side plane 22 and an electrode layer 27 is formed on the surface. The slide plane 23 is taken almost as projected plane made of the borader main body and constituted with almost perpendicular planes with the plane 22. Thus, the forming of the tip is made easy, and the fitting angle of a cunti-lever 3 is taken orthogonal with parallel plane between the electrode plane and the main body axial line, allowing to increase the accuracy of fitting angle.
