摘要： An optical pick-up device is provided that reduces aberrations in light irradiated from an optical recording meidu. The device includes a light source that outputs light for recordation and reproduction of information onto the optical recording medium. An objective lens irradiates the light onto the optical recording medium by concentrating the light. An actuator adjusts the movement of the objective lens to focus the light on at least one or more layers of the optical recording medium. A controller moves the objective lens to substantially reduce the aberration occurring in the light irradiated from the optical recording medium by driving the actuator, such that aberrations, such as asymmetrical aberrations or coma aberrations, may be reduced and corrected.

摘要： An optical pickup and an optical recording and/or reproducing apparatus adopting the same are provided. The optical pickup includes an optical unit, first and second objective lenses, and an optical path switching unit. The optical unit illuminates light onto an information storage medium and receives light reflected from the information storage medium to detect an information signal and/or an error signal. The first and the second objective lenses focus incident light to form a light spot on an information storage surface of the information storage medium. The optical path switching unit selectively directs the light incident from the optical unit to one of the first and second objective lenses. In the optical pickup, since the light quantity directed to a plurality of objective lenses may be maximized, optical efficiency is increased and thus high-speed operation may be attained.

摘要： A pickup actuator capable of significantly reducing rolling of the area, including: a pickup base, a lens holder having an objective lens mounted thereon, and lens holder driving means for driving the lens holder in directions for focusing and tracking on the pickup base. The lens holder driving means includes at least one magnet, a yoke for concentrating the magnetic flux of the magnet in the direction of the magnetic flux, and a driving coil having a focusing coil and a pair of tracking coils positioned between the magnet and the yoke. The respective widths of the magnet and the yoke are set at a rate of 1:0.8-1.2. Accordingly, the uniform magnetic flux area of the magnetic flux can be widely distributed in the width's direction of the yoke. Further, the magnet is attached to one side of one yoke while being slightly lowered thereon, so that the center of the magnetic flux of the magnet is downwardly moved from its initial position to a distance corresponding to 4-12% of the height of the magnet, and the center line of the magnetic flux of the magnet and the center line of the focusing coil are aligned with each other, exactly. Further, the width of the magnet and the gap between the pair of tracking coils are set at a rate of 1:0.6-0.9. Accordingly, the portions of the pair of tracking coils intersecting the effective magnetic flux area are positioned in the area where the density of the magnetic flux is low, so that the force in the focusing direction by the tracking coils can be reduced.
