Abstract:
An actuator unit including a friction drive actuator, a driving device for information recording/reading head, an information recording/reading apparatus and a method for driving the actuator unit which can achieve both high precision and high speed is provided by waiting the residual vibration to attenuate or forcibly attenuating the residual vibration to achieve high speed positioning by driving the friction drive actuator in the expansion and contraction mode after a high speed movement in the resonant drive mode.
