    摘要: An optical pickup actuator having: a moving part on which an objective lens to focus an incident beam onto an optical recording medium is mounted, a magnetic driver that drives the moving part in track and focus directions of the optical recording medium, and a support element that movably supports the moving part and has a first support portion with a first predetermined stiffness and a second support portion with a second predetermined stiffness different from the first predetermined stiffness. A center of gravity of the moving part, a center of support of the support element, and a center of a force determined by arrangement of the magnetic driver are coincident.

    摘要: An optical pickup and a lens assembling apparatus and a method thereof are provided. The optical pickup includes a plurality of objective lenses and a lens holder. The lens holder has a plurality of installation holes into which the plurality of objective lenses are inserted. In the lens holder, a seat surface of at least one of the installation holes is formed as a curved surface so that an inclination adjustment of the objective lens installed thereon can be performed. Since the seat surface of at least one of the installation holes provide to the lens holder is formed as a curved surface so that the inclination adjustment of the lens can be performed, the inclination adjustment between the plurality of objective lenses can be performed without an increase in the number of the parts or an increase in the number of the assembling processes.

    摘要: A CD-DVD compatible optical pickup in which both on-axis and off-axis light form a circular light spot on a recording surface of an optical recording medium, and an optical recording and/or reproducing apparatus using the same. The CD-DVD compatible optical pickup includes an optical output module, an objective lens, an optical path conversion unit, a photodetector, and an actuator. The optical output module has a mount and light sources emitting light of different wavelengths. The objective lens focuses the emitted light onto two types of optical recording media. The optical path conversion unit between the optical output module and objective lens, converts incident light. The photodetector receives beams emitted from the light sources, reflected from the optical recording media, and then passed through the optical path conversion unit, detecting data and error signals. The actuator has a movable member, moving the objective lens and compensating focusing and tracking error signals.

    摘要: An optical pickup actuator independently drivable in focusing, tilting and tracking directions. The optical pickup includes a lens holder movably installed on a base, and mounted with an objective lens for transmitting an incident light to an optical information recording medium; and a magnetic circuit to independently driving the lens holder in the focusing, tilting and tracking directions. The magnetic circuit includes opposing magnets; a focusing coil and tilting coils interposed between the magnets, mounted inside the lens holder, and wound around respective axes parallel to the focusing direction; and a plurality of tracking coils mounted outside the lens holder, interposed between the magnets and wound around respective axes transverse to the focusing direction. The magnetic fields of the magnets are guided by outer yokes partially encompassing the magnets and inner yokes positioned within the focusing coil and the tilting coils.
