A cable management system comprising a cable flex radius system having at least two opposing curved surfaces to control flex radius of a cable linking a stationary system to a dynamic system is disclosed. The cable management system also comprises a cable strain relief system comprising a cable clamp located on each of the at least two opposing curved surfaces. The system simultaneously provides position biasing of a driven rotating mechanism referenced to a fixed system as well as mechanism backlash control. The system insures consistent cable bend radius and slack management required to insure flex cable cycle life. In one embodiment, the cable management system is comprised of a torsion arm and a spool. In this embodiment, the torsion arm pivots during rotation of the spool. A spring connected to the torsion arm provides the requisite tension force to a cable that links the spool and the torsion arm. In this way, cable movement is controlled not only during operation of a moving mechanism, but also while the mechanism is at rest. Such control is particularly useful in devices which require precise movements, such as media storage devices.
