摘要： A semiconductor laser for generating a laser beam and an optical pickup for recording/reproducing information using the semiconductor laser as an optical source are provided. The semiconductor laser includes an aperture member on an emitting end thereof to perform high-density memory recording/reproducing through the reduction of an optical spot. The aperture has a hole whose diameter is smaller than the width of the active region of the semiconductor laser, to thereby restrictively emit the laser beam via the hole so that the optical spot formed on an optical disk is reduced. Thus, high-density memory recording/reproducing, which is useful for miniaturized information processors, can be realized.

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.

摘要： An optical pickup for correcting an astigmatic difference of a light by using a collimating lens arranged at an angle with respect to the thickness direction of an active layer of a light source and parallel to the width direction of the active layer, for collimating the light emitted from the light source, is provided. The collimating lens is arranged between an edge emitting laser diode having an active layer and a beam splitter, and corrects the astigmatic difference of the light emitted from the edge emitting laser diode. Therefore, a compact optical pickup can be achieved since additional optical elements for correcting the astigmatic difference of the laser beam are not required.

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： A recording/reproducing apparatus having an optical pickup device which is efficient in light use having little spherical aberration. The recording and/or reproducing apparatus includes an optical pickup having an objective lens, disposed opposite a disk, having a light passing region divided into central, intermediate and periphery regions corresponding to a near axis area, an intermediate axis area and a far axis area of incident light, where the curvature of the central and peripheral regions is optimized for a thin disk and that of the intermediate region is optimized for a thick disk, a light source irradiating light toward a disk through the objective lens; a photo detector for detecting light reflected from the disk, and a beam splitter, disposed between the objective lens and the light source, for transmitting light from the light source toward the objective lens and for diffracting light reflected from the disks toward the photo detector; and a processing unit to process an information signal to control the incident light generated by the light source, and to process the detected light from the photodetector. Therefore, the optical pickup device can be used for both compact disks (CDs) that are thick using light beam passing the near and intermediate regions of said objective lens, and digital video disks (DVDs) that are thin using light beam passing the near and far axis regions of said objective lens, and detect signals without picking up noise regardless of the thickness of the disk.
