A capacitive information disc playback stylus comprising a dielectric support element having in one portion a conical body terminating in a constricted tip. The tip comprises a curved prow surface, a flat electrode surface remote from the prow, shoulders joining the constricted tip to the conical body, and side surfaces which join the prow and the flat surface. The side surfaces, the flat surface, and the prow surface define the edges of a disc-engaging surface.
