A video record player includes a common drive belt for selectively translating a pickup stylus carriage. The player is equipped with a first drive mechanism, including a turntable-driven pulley, for utilizing the common drive belt for translating the carriage during playback toward the center of a turntable at a speed correlated to the speed of rotation of the turntable while stylus/record engagement is effected. The first drive mechanism includes a slip clutch interposed between the common drive belt and the turntable-driven pulley. In such players, a record caddy is used to push the carriage back to a starting position away from the turntable center, when it is at a position other than at the starting position during a caddy insertion into the player. A mechanism is provided for rendering the slip clutch disabled during a caddy insertion, whereby restoration of the carriage to the starting position can be effected with freedom from interference by the first drive mechanism, when the carriage is at a position other than at the starting position during such a caddy insertion.
