ABSTRACT:
A tangential pick-up device for a gramophone turn-table comprises a pick-up head on a support connected by a floating articulation to a carriage which is driven along a radially-disposed arm by a servo-control device to hold the support in a reference position. The floating articulation of the support, e.g. by flexible suspension wires, is arranged so that shocks or vibrations tend to cause pivoting of the support about two axes disposed radial and perpendicular to a disc and intersecting adjacent the pick-up needle, whereby jumping of the needle is avoided.
