ABSTRACT:
A pickup stylus adapted for playing back prerecorded signals from a disc record groove of a given width upon establishment of stylus/record relative motion has a dielectric support element which has a tip. The terminating portion of the tip is shaped to have a prow, a substantially flat rear surface remote from the prow, a pair of substantially parallel side surfaces extending from the side edges of the rear surface, a bottom surface extending from the bottom edge of the rear surface and additional surfaces extending from the prow and intersecting the bottom and the side surfaces. The stylus tip is dimensioned such that the maximum separation between the substantially parallel side surfaces is less than the given width.
