摘要 A method of manufacturing a stylus by modifying a square post shaped diamond element is disclosed. A tip having a conical surface is ground at one end of the diamond element. An electrode bearing surface is formed in the region of the tip such that the angle subtended by the electrode bearing surface with the axis of the element is not less than the angle included between the conical surface and the axis. A record engaging surface substantially orthogonal to the electrode bearing surface is formed in the tip region such that the two surfaces intersect along a line substantially perpendicular to the stylus axis. A thin layer of conductive material is deposited on the electrode bearing surface to form a stylus electrode.
