Abstract: Systems and methods are disclosed for an actuator device or actuator control device to implement a low power savings mode. For example, a device can comprise an actuator arm including a first actuator and a second actuator, the second actuator configured to refine a movement of the actuator arm to a more precise position than use of merely the first actuator. A device can also comprise a control system configured to determine when the device is in an idle state and, when the device is in the idle state, disable the second actuator and perform a positional seek operation with the second actuator disabled. Power savings can occur from disabling the second actuator, which may also include disabling associated circuitry, such that it does not consume power or consumes a nominal (e.g., negligible or insignificant) amount of power during the associated seek operation.
