There is provided a tilt correction processing method which can reliably detect the amount of tilt in a short time and adjust it, and then recording or replaying is started in a short time by employing the same. To perform recording or replaying to plural optical information media, an optical pickup having one or a plurality of light sources; one or a plurality of objective lenses for focusing light from the light source onto the optical information medium; an objective lens actuator which can control the objective lens in a focus direction and in a tracking direction and control the tilt of the objective lens; an optical information medium discriminating unit for discriminating a type of an optical disk when recording or replaying is performed to the optical disk; and an objective lens tilt setting unit for tilting the objective lens with respect to at least one of the optical information media by a predetermined amount by the objective lens actuator based on the discriminated result of the type of the optical information medium.
