Abstract
PURPOSE:To prolong the life of a reproducing stylus, by providing a part whose length in the direction perpendicular to a relative slide direction is longer than that of a successive connection part between a sliding surface and an electrode- formed surface, to the sliding surface of the reproducing stylus. CONSTITUTION:A reproducing stylus 29 consists of a reproducing stylus body 105 made of diamond, etc., and a conductive electrode 100 adhered to the electrode- formed surface 107 of the body 105. At the tip part of the body 105, a sliding surface 103 is formed; its lead-in part 102 is formed as a vertex, from which a ridge 106 is extended slantingly upward. The contact lengthwise size and widthwise size 104 of the sliding surface 103 is set greater than the width 101 of the edge of the electrode 100 in a direction perpendicular to the direction of a relative slide on a disk, thereby setting the area of contact with a disk surface much greater than that of information bits.
