報記録再生装置。[Claims for Utility Model Registration] Optical information recording for recording information on an information recording medium by irradiating the information recording medium with laser beams of two different wavelengths, and reproducing the information recorded on the information recording medium. In the reproducing device, one laser beam source that emits laser beams of two different wavelengths, a first wavelength and a second wavelength; a reflective and transmissive element that reflects and transmits the laser beam emitted by the laser beam source; a first organic dye film that allows only a laser beam of a first wavelength to pass among the laser beams reflected by the reflective-transmissive element; and a second organic dye film that allows only a laser beam of a second wavelength to pass among the laser beams that have passed through the reflective-transmissive element. an organic dye film; a first focusing element that focuses a laser beam of a first wavelength that has passed through the first organic dye film onto the information recording medium; and a laser beam that has a second wavelength that has passed through the second organic dye film. An optical information recording/reproducing device comprising: a second condensing element that condenses a laser beam onto the information recording medium.
