Abstract: An optical pickup device according to an embodiment of the present invention comprises a light source for projecting a beam of light to record and reproduce information with respect to an optical recording medium. A collimating lens is disposed on a path of the light to converge and convert the light into a parallel beam. An object lens condenses the parallel beam from the collimating lens and projects the parallel beam onto the optical recording medium. An optical element is disposed between the collimating lens and the object lens. A first actuator moves the collimating lens along the optical axis to thereby control a distance between the collimating lens and the optical element. A first controller drives the first actuator to find a position for the collimating lens, for reducing aberration generated in the light being projected to the optical recording medium. Accordingly, the aberration can be effectively prevented, thereby improving recording and reproducing performance of the optical pickup device.

Abstract: 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.
