PURPOSE:To obtain a recording and reproducing element with long life by increasing the wear resistance of the element and the adhesive strength to diamond for a PCM audio disc and a video disc, by forming an electrode with nitride in which N is invaded to a transition metal such as Ti. CONSTITUTION:An electrode 6 of a reproducing stylus 1 is formed with a transition metal-invaded compound such as Ti, V, Zr, Nb, Hf, Ta, Y, Mo and W. The electrode 6 is adhered to diamond of the stylus 1 with a physical vapor deposition method such as ion plating of the said metallic nitride or a chemical vapor deposition method using a gas (TiCl4) including a transition metal. The bonding force to diamond is strong, no peeling is caused, the hardness is high, excellent wear resistance is given, and the recording and reproducing element with long life and high reliability can be obtained. |
