摘要： A diffractive optical element emits substantially zero order diffracted light when light with a wavelength of 0.35 μm to 0.45 μm is incident and emits substantially first-order diffracted light when light with a wavelength of 0.6 μm to 0.7 μm is incident. The diffractive optical element includes a substrate and a grating portion formed on the substrate. The grating portion has a step-wise cross section with any one of levels selected from four levels, five levels and six levels. The diffractive optical element emits substantially zero-order diffracted light when light with a first wavelength λ1 satisfying the relationship: 0.35 μm≦λ1≦0.45 μm is incident and emits substantially first-order diffracted light when light with a second wavelength λ2 satisfying the relationship: 0.6 μm≦λ2≦0.7 μm is incident.

摘要： An optical head with excellent optical characteristics even when using a light source that substantially has a wavelength broadening is provided. The optical head includes a light source, an objective lens for focusing a light beam emitted from the light source on an information recording medium and a photodetector for detecting the light beam reflected from the information recording medium, wherein defocusing correction means and spherical aberration correction means are provided in an optical path between the light source and the information recording medium. Since both the defocusing correction means and the spherical aberration correction means are provided, while defocusing of a focused spot on the information recording medium caused by a wavelength broadening of the light source and chromatic aberration of the optical system can be corrected, the spherical aberration of the optical system caused by wavelength difference between a design wavelength and an incident wavelength also can be corrected. As a result, excellent optical characteristics can be obtained.

摘要： An information recording and reproducing apparatus in accordance with the present invention has a radiation light source, a collimator turning a light beam emitted from the radiation light source into substantially parallel light, a light beam convergence member focusing the light beam on an information carrier, a light beam polarization-branching member branching the light beam by polarization, a variable wave plate located between the collimator and the light beam convergence member, photo detectors receiving the light beam branched by the light beam polarization-branching member and outputting a current according to an incident light quantity, and an output level judging member judging whether an output of the photo detectors is larger or smaller than a predetermined value. When the photo detectors receive a small light quantity because the information carrier is highly birefringent, the variable wave plate is switched from a ¼ wavelength plate to a zero-wave plate, thus constantly obtaining a stable reproducing signal with an excellent S/N.
