CONSTITUTION: A laser beam of an LD(Laser Diode,21) is converted into wave and half wave beams through an SHG(Second-Harmonic Generation) element(22). Two wave beams are filtered to wave and half wave beams by a wave selector(23). The wave and half wave beams are emitted to a disk(D) and passed through a wave guide lens(24) to read data of the disk. Then, the beams are focused on the disk by objective lenses(25,25'). The beams are passed through the objective lenses and the wave guide lens again to detect the amount of light from the disk data by a photodetector(26). The passing part of the half wave beam of the wave guide lens has short waves. Thereby, the half wave passing part is used for high-density reading and writing. The other part of the wave beam is used to detect a focus error and tracking error for reading. Therefore, a pick-up system is available for reading and writing disk data.
