Patent attributes
It is an object of the present invention to provide an optical pickup device being capable of correcting coma aberration induced in a light-condensing optical system including an objective lens for an optical disc and having a reduced size and a reduced thickness in comparison with the conventional art. The present invention includes a first coma-aberration correction actuator (6) including a first tilt drive portion for inclining an objective lens in a first tilt direction, and a second coma-aberration correction actuator (7) including a second tilt drive portion for inclining, in a second tilt direction, a coma-aberration correction lens placed between a light source and a raising mirror for reflecting emitted light toward the objective lens.
