    摘要: An optical pickup apparatus capable of reading information from recording media of different read wavelengths, includes a light-emitter having a first light source for emitting a first laser beam integrated with a second light source for emitting a second laser beam of a different wavelength from that of the first laser beam. The optical pickup apparatus includes a photodetector for receiving a beam reflected by each of the recording media and an optical system having a plurality of optical elements which form an optical path to guide the first and second laser beams to the recording media and which form an optical path for guiding the reflected beam to the photodetector and through which the first and second laser beams pass.

    摘要: Laser beams h1, h2 with different wavelengths emitted from semiconductor lasers 2a, 3 are incident to an optical path joint prism 13 and each of optical intensities of the laser beams h1, h2 is detected by a photoelectric conversion element 15 provided in an optical path integrated by the optical path joint prism 13 on which a semi-transmission film HM is provided and APC control of each of light emission intensities of the semiconductor lasers 2a, 3 is performed on a basis of each of detection results. As a result of this, the beam intensity of the laser beam h1 passing through the optical path joint prism 13 to be applied to an information recording medium and the laser beam h2 reflecting the optical path joint prism 13 to be applied to the information recording medium are controlled properly.

    摘要: A reflective mirror 14 is inclined and placed with respect to an objective lens 16 and a photoelectric conversion element 15 for monitor is placed in the back side of the reflective mirror 14. The reflective mirror 14 is formed into a structure in which a semi-transmission film HM having predetermined reflectance and transmittance is formed on one surface of a substrate of a transparent medium. When a laser beam for information record or information reproduction is launched from semiconductor lasers 2a, 3 to the reflective mirror 14, the semi-transmission film HM splits the laser beam into a reflected beam and a transmitted beam and the reflected beam is emitted to the side of the objective lens 16 and the transmitted beam is emitted to the side of the photoelectric conversion element 15. As a result of this, any laser beams for the information record and the information reproduction can be detected by one photoelectric conversion element 15 to perform APC control of the semiconductor lasers 2a, 3 and the intensity of the laser beam for the information record and the information reproduction with respect to an information record medium can be controlled properly.
