Abstract
A video disc player includes a turntable for centering and rotatably supporting a record for playback. A pickup stylus for recovering information stored on a turntable-supported record during playback is mounted in a carriage. A play belt is provided for translating the carriage toward the turntable center at a speed correlated to the speed of rotation of the turntable. A search belt is provided for translating the carriage toward and away from the turntable center at a speed independent of the speed of rotation of the turntable. A mechanical toggle switch is mounted to the carriage for motion between a first location, a second location and a third location. The toggle switch in the first location connects the carriage to the play belt to the exclusion of the search belt. When disposed in the second location, the toggle switch frees the carriage from both belts. The toggle switch secures the carriage to the search belt, to the exclusion of the play belt, while occupying the third location. In accordance with a further feature of the invention, an additional mechanism is provided for disposing the toggle switch into a selected one of the locations.
