1. A device comprising:
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 control system configured to:
determine when the device is in an idle state indicating the device should enter a power saving mode;
based on the device being in the idle state, disable the second actuator to save power, and perform a positional seek operation to position the actuator arm with the second actuator disabled; and
when the device is not in the idle state, perform a positional seek operation for the actuator arm utilizing the first actuator and the second actuator to position the actuator arm.
