Abstract:
A HDD including a temperature sensor for sensing ambient temperature in the HDD, a spindle motor comprising a fluid dynamic bearing; and a controller configured for adjusting a rotational speed of the spindle motor based on the measured ambient temperature while a rigidity of the fluid dynamic bearing is maintained, and reducing power consumption of the HDD based on the adjusting the rotational speed of the spindle motor.
