摘要： An optical pickup includes a lens holder holding an objective lens for converging a light beam on a signal recording layer of an optical disk; elastic support members supporting the lens holder such that the lens holder can freely move in three driving directions, i.e., a tracking direction, a focusing direction, and a tilting direction; a pair of coil units attached to two sides of the lens holder, the two sides being spaced in a tangential direction orthogonal to the focusing direction and tracking direction; and a pair of magnets arranged to face the corresponding coil units. Each coil unit includes a tracking coil, a focusing coil, and a tilting coil for driving the lens holder in the three driving directions. The focusing coil and the tilting coil are formed by winding a focusing conductor of the focusing coil and a tilting conductor of the tilting coil together in parallel.

摘要： The actuator is used in a pickup device for a drive device of an optical disc. The actuator is positioned opposing to the optical disc to irradiates a light beam from a light source to an information recording surface of the optical disc. The objective lens is fixed at on the lens holder forming the actuator at a position closer to one end thereof. One coil substrate is fixed on one side face of the lens holder in a range from the one end of the lens holder to a center portion of the lens holder, and the other coil substrate is fixed on the other side face of the lens holder in a range from the other end of the lens holder to the center portion of the lens holder. Therefore, near the end of the lens holder on the objective lens side, the coil substrate is not attached to one side of the lens holder, providing a space below the objective lens. By arranging an optical system to guide the light beam to the objective lens via the space, the optical system can be arranged at the same height level as the actuator.

摘要： The pickup device is used in a drive device of an optical disc and is opposed to the optical disc to irradiate a light beam from a light source onto an information recording surface of the optical disc. The pickup device has the actuator including the objective lens for condensing a light beam on the information recording surface of the optical disc, and irradiation of a light beam on the optical disc is controlled by moving the objective lens. Further, the pickup device has the optical system for directing a light beam, which is emitted from the light source, to a position below the objective lens. The optical system is placed at the same height level as the actuator. Therefore, as compared with the case where the optical system is provided below the actuator, the whole pickup can be smaller in thickness, and it is possible to provide a pickup device suitable for a thin drive device.
