1, the light is focused to a predetermined diameter and recorded on the recording surface (32a) (32b) of the information recording medium (Inc.) as shown in FIG. On the other hand, the reflected light from the information recording medium @4 is separated by a beam splitter and enters the photodiode. The polarizing beam subric reflects or passes only polarized light at a predetermined angle, so it separates the light by adjusting the polarization angle. Therefore, the linearly polarized light from the semiconductor laser becomes circularly polarized by the 1/4 wavelength plate, and the direction of rotation of the circularly polarized light from the information recording medium changes, resulting in 1/4 wavelength plate.
After passing through the four-wavelength plate, the light becomes linearly polarized at 90 degrees to the incident light, so it passes without being reflected by the beam splitter.
