ABSTRACT:
An optical system comprises an objective lens for moving along a recording face of an optical disk in the radial direction of the optical disk so that an optical axis thereof is almost perpendicular to the recording face, a reflecting mirror for moving together with the objective lens and whose reflecting axis extends in the radial direction, a detection optical unit, a movable mirror located to incline with respect to the optical axis extending almost parallel to the recording face from the detection optical unit and the reflecting axis of the reflecting mirror, and a mirror drive portion for rotating the movable mirror on an axis almost parallel to the recording face and shaking a light beam radiated from the objective lens onto the recording face in the radial direction. The mirror drive portion rotates the movable mirror on an axis almost parallel to an optical axis extending from the detection optical unit or on an axis almost parallel to a reflecting face of the movable mirror. Reflecting axes of the reflecting face are disposed on the same plane parallel to the recording face.
