Abstract
The audio signal-to-noise ratio obtainable in a capacitance electronic disc system which includes a conductive disc formed from a plastic resin containing conductive particles and a playback stylus is increased by spacing the playback stylus at a slight distance from the surface of the conductive disc. This spacing can be attained by depositing a thin coating of a dielectric material on the surface of the conductive disc.
