Disclosed is an optical pickup apparatus having a limited optical system of the comma aberration compensating type. The apparatus comprises an object lens(13), an actuator(14), an actuator bobbin(22), a suspension plate(24), a base apparatus(26) and an elastic supporter(25). The elastic supporter(25) is installed between the suspension plate(24) and the base apparatus(26). The elastic supporter(25) rotates an actuator bobbin(22) when the object lens(13) moves to the tracking direction, so that the location of the object lens(13) is accurately regulated by compensating.
