Abstract

PURPOSE:To manufacture a line contact record disc stylus, by performing a process of cutting off a part of a stylus having a cone shape tip with two planes with a prescribed angle after the polishment of the tip of the stylus. CONSTITUTION:A curved surface 21 with a prescribed curvature is formed to a prescribed direction of a stylus 20 having a cone-shaped tip and the polishment of a bottom surface 24 is also finished. Thereafter a part of the stylus 20 is cut off with two planes having a prescribed angle to form planes 22 and 23 with ends 22a and 23a. In forming the ends 22a and 23a, a contact part 25 viewed from the prolonged line of the top of the cone of the stylus 20 shows an almost ideal straight line.
