    摘要： Provided is an optical pickup device that compensates for an aberration caused by a beam splitter. When a beam of light is reflected from a disc and proceeds towards a beam splitter, the beam splitter is designed to allow the reflected beam to pass therethrough. However, the beam splitter can cause an astigmatism in the reflected beam due to diffraction. According to various aspects herein, an optical pickup device may include a compensation device that generates an inverse astigmatism to compensate for the astigmatism generated by the beam splitter.

    摘要： An objective lens for optical pickup and an optical pickup apparatus having the same are provided. The objective lens for optical pickup includes a light source side lens surface and a disc side lens surface. The light source side lens surface and the disc side lens surface each include an effective region disposed at a central region of the objective lens and a non-effective region disposed outside the effective region. An optical path changing element, disposed in the non-effective region of at least one of the light source side lens surface and the disc side lens surface, changes a path of light incident thereon.

    摘要： An optical information recording/reproducing apparatus for recording information on a recording medium and/or reproducing information from the recording medium, includes: a laser light source for performing recording and/or reproducing information; a shielding part, using a liquid crystal, that can switch between transmission and interception of laser light emitted from the laser light source; a driving circuit for driving the switching between transmission and interception of the shielding part; a moving part for relatively moving the shielding part and the laser light; and a controlling circuit for controlling the moving part. The moving part relatively moves the shielding part and the laser light so as to switch a region to which the laser light is applied from a first region of the shielding part to a second region thereof different from the first region, in order to prevent the liquid crystal from deteriorating.
