ABSTRACT:
An optical head apparatus wherein a lens holder which holds an objective lens for condensing a light beam on an optical recording medium is turned in a plane perpendicular to an optical axis of the objective lens and one portion of construction members of turning unit for performing a tracking control for the optical recording medium is fixed to a fixed body. One or some of construction members of the turning unit for tracking control is not mounted to a moving body for supporting the lens holder but is mounted to the fixed body, as a result, weight of a movable unit including the moving body and its loading members is to be reduced to realize high-speed access with respect to the optical recording medium.
