Abstract: An optical information processing apparatus includes a scanning device for scanning an information track on an optical recording medium by a focused light spot, a moving device for moving the light spot in the direction of an optical axis of the scanning device and/or in a direction which is perpendicular to the optical axis with respect to the information track, a detecting device for detecting focusing and/or tracking error signals of the light spot with respect to the information track, a control device for returning the detected error signal to the moving device, a limiting device for electrically limiting a range of movement of the light spot, and an adjusting device for adjusting the range of movement of the light spot which is limited by the control device in accordance with a sensitivity of the moving device.
