Three degrees of freedom (parallel, pitch, and rolling modes) were enabled for the head in order to apply a load to the head to balance the acting floating blade and to follow the undulations of the medium. However, the magnetic head support vibrates and resonates due to wind, protrusions on the arm and medium surface, and dust colliding with the head, causing floating and fluctuation.
