REPRODUCING STYLUS OF VARIATION DETECTING TYPE REGENERATION ELEMENT OF ELECTROSTATIC CAPACITY VALUE

摘要

PURPOSE:To attain to make a reproducing stylus having stabilized reproduction characteristics have a long life, by forming an electrode part in the inorganic bad conductor layer seaming materials of wear-proof. CONSTITUTION:An electrode material is stuck and filled in the concave space which is surrounded by the materials having wear-proof Sa and Sb, and the inorganic bad conductor layer C by which the materials Sa and Sb are seamed. Moreover, an electrode end which is in sliding contact with a disk exists inside the sliding contact part A of the reproducing with a disk exists inside the sliding contact part A of the reproducing stylus. The shape and dimensions of the electrode part E are decided by the sectional shape and dimensions of the concave part formed on the layer C which has been placed in order to seam the materials Sa and Sb. Furthermore, the electrode width is decided by width W of the concave part formed on the layer C. Resulting from the foregoing, the adhering status of the electrode material becomes satisfactory and the electrode part is protected satisfactorily, therefore the electrode width appearing on the sliding contact surface A can be made constant at all times even if the reproducing stylus is worn.
