Low friction linear tracking tone arm

This invention is provides a means of playing LP records with minimal distortion. Low distortion is achieved by eliminating tracking error normally associated with pickup cartridges mounted to pivoting tone arms. This invention discloses a tone arm that constrains the motion of the stylus to straight radial path, mimicking the cutting path of the record lathe, supported on parallel rails by free rolling spherical bearings.

In the preferred embodiment, the fixed rods or tubes are driven synchronously, thereby eliminating static friction of the supporting rolling balls. Friction is further reduced using magnetic or buoyant support of the tone arm to reduce bearing load to that amount minimally sufficient to maintain full contact between the rolling balls and the upper and lower rods.
