ABSTRACT:
Apparatus for sharpening a diamond cutting stylus for use in recording video signal information in a metal master includes a source of high energy particles such as an ion milling machine. The high energy source provides a beam of high energy particles having a cross-sectional area perpendicular to the longitudinal axis of the beam that is large compared to a given area on a mounting face of the stylus which is to be bombarded by the beam during the sharpening operation. Further, the apparatus includes a masking block for masking a first portion of the cutting stylus. The masking block is positioned with respect to the high energy source to intercept the particles in the beam directed at the first portion of the cutting stylus. A second portion of the cutting stylus which includes the given area is exposed to the high energy particles such that the second portion of the cutting stylus is removed.
