The object of the present invention is to propose an optical disk driving apparatus, an optical disk driving method and an optical disk apparatus capable of reducing the occurrence of disturbance to focus servo control and tracking servo control. Each wire drawing unit comprises: a dancer roller for applying back tension to the wire; a wire drawing die for reducing the diameter of the wire; and a capstan for winding and transporting the wire without slip to apply front tension to the wire. The casings are mounted to the same side of the truck on which the hose manifolds are located. An annular, rotatable locking collar attaches to the mount body and extends over the locking spring.
