摘要： A light emitting module and method for shaping a beam via a beam shaping window and an optical pickup apparatus employing the same. The light emitting module includes a base, a semiconductor laser that is installed on the base and emits a laser beam of a predetermined wavelength, a cap surrounding the semiconductor laser, a beam shaping window that is fitted with a predetermined portion of the cap corresponding to the propagation path of the laser beam and shapes a transmitted laser beam while reflecting a portion of an incident beam, and a monitor photodetector that is disposed within the cap and receives the laser beam reflected by the beam shaping window in order to monitor the laser beam emitted by the semiconductor laser.

摘要： Disclosed is an optical pickup including a polarization holographic optical element (HOE) and a photodetector. The optical pickup includes a light source, an optical path changer, an objective lens, a polarization HOE, and a photodetector. The polarization HOE has a pattern designed to generate different astigmatisms in the left and right halves of the polarization HOE in a tangential direction and to divide plus and minus first-order beams in a radial direction. The photodetector includes a first light-receiving portion receiving a zero-order beam and second and third light-receiving portion that are disposed on either side of the first light-receiving portion in the tangential direction and respectively receive the plus and minus first-order beams.

摘要： A method of reproducing information from an optical disc, and an optical disc reproducing apparatus using the method, including reproducing information from an optical disc having a plurality of regions with differing physical specifications, the information is read using optical beams having differing spot sizes in regions of the optical disc having differing physical specifications. The method enables the optical disc having the regions with differing physical specifications to stably reproduce information from all regions of the optical disc by minimizing regional reproduction performance differences caused in the reproduction process.

摘要： A compatible optical pick-up apparatus, which records to and/or reproduce from both digital versatile disc (DVD)-type optical disks and compact disc (CD)-type optical disks for improving a signal regeneration capacity and a tracking capacity in operation at a high temperature. A polarized hologram of the optical pick-up apparatus is divided into six diffraction regions. The rays of a first light diffracted at the first and second diffraction regions are separately received by divided parts of a first bisected light-receiving portion of a photodetector.
