Abstract
A disc recorder includes a rotating recording disc and a transducer carriage which is transversely movable with respect to the axis of rotation of the rotating disc. The transducer carriage includes a mounting surface which is substantially perpendicular to the rotating disc and substantially parallel to the direction of movement of the carriage. A transducer holding plate is positioned adjacent and parallel to the mounting surface and a parallel motion linkage attaches the holding plate to the carriage. The linkage confines the motion of the transducer holding plate in a plane parallel to the mounting surface to motion which is substantially perpendicular to the rotating disc. A spring is provided biasing the holding plate against the mounting surface and biasing the holding plate toward the rotating disc. The transducer is positioned on the holding plate such that it coacts with the rotating disc. Friction reducing pads may be positioned between the mounting surface and the transducer holding plate.
