摘要： Various embodiments are generally directed recurringly cycling the driving of a platter media of a hard drive with a motor, allowing rotation of the platter media to slow only to a threshold rotational speed to balance power conservation with delays in accessing data. A method comprises driving platter media of a hard drive to rotate at a selected normal rotational speed, retrieving data stored on the platter media when the platter media rotates at the normal rotational speed, ceasing to drive the platter media to rotate to allow the platter media to rotate under rotational inertia imparted to the platter media, monitoring a current rotational speed of the platter media, and resuming driving the platter media to rotate based on the current rotational speed falling to a lower threshold rotational speed selected to be less than the normal rotational speed. Other embodiments are described and claimed.
