摘要： According to one embodiment, a diffraction pattern of a diffraction element, or a hologram polarization element, to guide a reflected laser beam divided into a predetermined number to a photodetector is combined preferably as one unit, in order to provide an optical head unit and an optical disc apparatus, which provides a stable reproducing signal, irrespectively of the standards of recording media, when reproducing information from a recording medium of optional standard. By using this diffraction pattern, it is possible to obtain outputs usable to detect first, second and third signals used to detect a tracking error when reproducing information recorded on an optical disc from a reflected laser beam from an optical disc, a fourth signal used to detect a focus error, and a fifth signal used to detect a disc tilt error and a spherical aberration compensating component.

摘要： A focus servo control device includes a first detector, first controller, second detector, and second controller. The first detector detects a first focus error signal. The first controller controls the objective lens based on the first focus error signal, so that a focal point of the first laser agrees with the guide layer. The second detector detects a second focus error signal. The second controller changes a relative distance between the focal point of the second laser and the focal point of the first laser, so that the focal point of the second laser agrees with a target recording/reproducing layer.

摘要： According to one embodiment, an APC photodetector accepts a light beam branched from a light beam toward a recording medium by a branching mirror and detects intensity of a light beam supplied from a light source, a light quantity adjusting element adjusts the intensity of the light beam, and the intensity of the light beam incident to the APC photodetector is changed in a continuous manner or a stepwise manner by the light quantity adjusting element. Therefore, when the single APC photodetector detects recording and reproducing light beams, the recording and reproducing light beams can fall within a dynamic range of the APC photodetector.
