<P>PROBLEM TO BE SOLVED: To provide an optical pickup device in which highly accurate positioning adjustment of an objective lens and a wavelength compatible element can be performed, a member for attaching both is miniaturized and made light in weight, and drive characteristics of a lens actuator are not deteriorated. <P>SOLUTION: The optical pickup device comprises: a pickup base 22; a light source part 24 for outputting a plurality of light beams corresponding to a plurality of disk formats; a single objective lens 6 for converging light on the optical recording medium of different thickness; the wavelength compatible element 2 for correcting an aberration generated when converging the plurality of light beams on the optical recording medium of the different thickness; and a lens actuator 28 provided with an actuator movable part 30 for driving the objective lens and provided on the pickup base. In the optical pickup device, to the actuator movable part 30 of the lens actuator, the objective lens and the wavelength compatible element are adhered and fixed in the state of being mutually positioned and adjusted. <P>COPYRIGHT: (C)2007,JPO&INPIT |
