A disc recorder has a rotating recording disc and a transducer assembly, including a transducer, which cooperates with the disc. A carriage is provided for mounting the transducer assembly. An idler pulley and a drive pulley, one of the pullies being inward from the periphery of the disc and the other pulley being positioned outward of the disc from the first pulley cooperate with a carriage belt arrangement which is attached to the carriage and to the drive pulley and which extends around the idler pulley. The carriage belt arrangement includes first and second carriage belts which are each attached at one end to the carriage and at their other ends to the drive pulley. Additionally a third carriage belt is attached to the carriage and extends in the opposite direction from the first and second belts and is attached to the drive pulley intermediate the first and second carriage belts.
