Abstract
A stylus tip is fabricated from a portion of a synthetic diamond stone having a plurality of facets oriented along the {100} family of planes. The portion is bounded by a right circular cylinder having a base thereof centered along one of the {100} facets having a surface area larger than the average surface area of the {100} facets, and having a base diameter and height equal to about half the width of the one facet.
Claims8
A method of fabricating a stylus tip, adapted to track a path along the surface of an information record, from a synthetic diamond stone having a plurality of facets oriented along the {100} family of planes, said facets having an average surface area, comprising the steps of:
- selecting from said plurality of facets one facet having a surface area larger than said average surface area, and
- fabricating said entire tip from a portion of said stone bounded by a right circular cylinder having a base thereof centered along said one facet, said cylinder having a base diameter and height equal to about half the width of said one facet.
In a stylus tip fabricated from a synthetic diamond stone having a plurality of facets oriented along the {100} family of planes, said facets having an average surface area, the improvement comprising said entire tip being a portion of said stone bounded by a right circular cylinder having a base thereof centered along one of said facets having a surface area larger than said average surface area, said cylinder having a base diameter and height equal to about half the width of said one facet.
