摘要： A compatible optical pickup including an optical unit and a focusing unit. The optical unit emits a short wavelength light for high-density recording media and a long wavelength light for low-density recording media, directs the short and long wavelength light to a recording medium, receives lights reflected by the recording medium, and detects an information reproduction signal and/or an error signal from the received lights. The focusing unit focuses light received from the optical unit to form a light spot on a recording surface of the recording medium, diffracts the short wavelength light into a zero order light and the long wavelength light into a second order light to be used as effective light for recording and/or reproduction. Thus, a high-density recording medium and a low-density recording medium having different thicknesses can be compatibly used.

摘要： In an optical pickup, a focus error detector for detecting a focus error of an objective lens for an optical disk includes a focusing lens for focusing the reflected light of the optical disk, a diffraction optical device for diffracting the reflected light focused by the focusing lens into two light rays, two bi-segmented photo-detectors for receiving the two split light rays, respectively, and a circuit for outputting a desired focus error signal from the signal detected from the photo-detectors. The circuit outputs a pure focus error signal without errors created by the deviation of the light amount in the photo-detectors due to the tilt or shift of the reflected light, thereby contributing to the stable operation and miniaturization of the optical pickup.

The objective lens device includes an objective lens arranged along an optical path parallel to the disks, and first and second control portions formed in a light incident surface of the objective lens, a light emitting surface thereof, or an extra transparent member.

摘要： In a method and an apparatus for correcting aberration due to optical disk tilt, the apparatus includes a correction plate through which a first light beam passes by an object lens in an optical disk, a light source and a photo detector for generating and receiving a second light beam to detect the magnitude of the optical disk tilt, respectively, and an actuator for inclining the correction plate based on the detected signal. The correction plate has the same optical properties as those of the substrate of the optical disk, irrespective of the optical pick surroundings and offset the aberration due to the optical disk tilt. Therefore, while the best performance of the optical pickup is ensured, adverse effects caused by the aberration due to the optical disk tilt can be eliminated through simple circuitry.

摘要： An optical pickup for recording and/or reproducing data with respect to a multilayer recording medium having a plurality of recording layers, where the optical pickup includes a light source emitting a beam having a predetermined wavelength, a diffraction unit separating the beam emitted from the light source into a main beam and a sub-beam, and a photodetector having a main photodetector detecting a main beam reflected from the multilayer recording medium and a sub-photodetector detecting the sub-beam. In the optical pickup, the main photodetector and sub-photodetector are separated a predetermined distance from each other so that a beam spot formed by the beam reflected from a defocus recording layer is not detected by the sub-photodetector.
