ABSTRACT:
A diamond body is heated in an environment of vacuum or inert gas containing a small amount of oxygen at a predetermined elevated temperature to allow the carbon atoms of the surface areas to form a layer of graphite on the diamond body. The diamond body is then lapped so that the graphite layer is shaped into the form of a stylus electrode.
