摘要： In an optical pickup device, an objective lens unit includes a first lens, a second lens for converging a light beam which passed through the first lens on an information recording layer of a recording medium, and a second-lens-driving-use actuator for adjusting the distance between the first and second lenses. The second lens has a reflecting section for reflecting an outer part of the light beam which passed through the first lens and reached the second lens. Moreover, the optical pickup device includes a condenser lens, a cylindrical lens and a light receiving element for detecting a reflected light beam reflected by the reflecting section, and a control device for detecting the distance between the first and second lenses according to the result of detection and for controlling the second-lens-driving-use actuator according to the result of detection. With this structure, the occurrence of spherical aberration due to an error in the thickness of a cover glass of the recording medium and variations in the thickness of the objective lens is limited.
