摘要： An optical pickup device for condensing the light from a light source on a signal recording surface of an optical recording medium, such as an optical disc (20). A semi-spherical lens (9) of the optical pickup device has a surface (9b) facing an optical disc (20) and has a pre-set refractive index. The optical pickup device also has a slider (12) adapted for securing the lens (9) and for being in sliding contact with an optical disc (20), and a spring plate (13) adapted for thrusting and supporting the slider in sliding contact with the optical disc (20). With the optical pickup device, high density reproduction may be realized, while the tolerance value for warping during disc molding or the tolerance value for warping due to moisture absorption may be increased. In addition, the production yield and the degree of freedom in selecting the disc materials may be improved.
