ABSTRACT:
An information signal track search system in a rotary recording medium reproducing apparatus comprising a reproducing transducer having a cantilever provided with a reproducing element and being resiliently supported at a part in the vicinity of a rear end thereof, and a moving circuit for moving the reproducing transducer along a radial direction of the rotary recording medium, comprises, a detecting circuit for detecting that the reproducing element has reached a desired set track position, a movement stopping circuit for stopping the movement of the moving circuit according to an output of the detecting circuit, where the reproducing element lags the rear end of the reproducing transducer while being moved by the moving circuit due to frictional force between the rotary recording medium and receiving a force urging further advancement along the moving direction due to a restoration force of the cantilever after being stopped by the movement stopping circuit, and a forcibly moving circuit for applying a force to the reproducing element for forcibly moving the reproducing element in a direction opposite to the moving direction after the reproducing element is stopped by the movement stopping circuit, to finally move the reproducing element to the desired set track position.
