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.
