To eliminate scratches on a disc surface of an optical disc in an emergency eject operation, there is provided an optical disc apparatus including: an emergency eject detector for detecting an emergency eject instruction; a rotation speed detector for producing a signal corresponding to the rotation speed of the optical disc; and a logical circuit unit which is operated by a first signal from the emergency eject detector and a second signal from the rotation speed detector, and when the second output signal is not more than a reference level, produces a third signal so as to input a control signal for instructing stop of the actuator control into an actuator controller. After detection of the emergency eject instruction, the apparatus performs the actuator control without producing the third signal until the rotation speed is not more than a predetermined value. Thus the objective lens is made in a focus control state or in a saving state in which the objective lens is separated from the disc surface.
