ABSTRACT:
A straight line tracking turntable sound reproducing system. A conventional rotatably mounted turntable is unconventionally mounted on linear tracks for linear travel toward a substantially fixed position pivotally mounted stylus-carrying tone arm.
A servomechanism comprising a sensing device and a motor means controls the rate of linear travel of said turntable so that displacement of said tone arm is minimized. The sensing device detects displacement of the tone arm and signals the motor means to increase or decrease the rate of turntable linear motion as required.
Mechanical pinch clutch means are provided to allow manual re-positioning of said turntable to any pre-selected position along its linear path.
