付着させていた。The structure of the conventional example and its problems A disk-shaped recording medium (TISF) in which information signals are sequentially recorded in a concave and convex shape (focus) so as to form a spiral recording trajectory on the disk-shaped recording medium is rotated and driven. In a capacitance type reproducing device, the recording locus is scanned by a reproducing needle having an electrode attached to the side surface of a pyramid-shaped needle base made of, etc., and the uneven shape is detected as a change in capacitance by the electrode. The regenerating needle requires metallizing the surface of a substrate made of diamond or the like, and conventionally a metal coating, for example, has been deposited directly on the diamond surface by vacuum deposition.
