Abstract

PURPOSE:To contrive to prevent degradation of S/N, output, etc., by forming the electrode growing a homoepitaxial crystal on the main body of reproducing stylus consisting of single crystal of a substance with high specific resisstance; the homoepitaxial crystal is of the same kind as or different kind from the single crystal of the stylus, and has a small specific resistance.
