    摘要: A recording medium includes at least one recording layer on which information is recorded by multi-photon absorption, and a servo layer disposed in a laminated direction with respect to the recording layer and having a track for guiding a beam spot of laser light having a first wavelength and a beam spot of laser light having a second wavelength along a scanning trajectory. The servo layer and the at least one recording layer constitute a set of layers, and a plurality of sets of layers is formed in the laminated direction. The servo layer is made of a material having a high reflectance with respect to laser light having a third wavelength for generating a servo signal, and low reflectances with respect to the laser light having the first wavelength and the laser light having the second wavelength.

    摘要: A servo objective lens and a recording/reproducing objective lens are commonly held on a holder. The servo objective lens and the recording/reproducing objective lens are integrally displaced, thereby pulling servo light onto a servo layer. Upon the pulling, focus positions of recording light and reproducing light follow a focus position of the servo light. As a result, the focus positions of recording light and reproducing light are set close to the servo layer. Thereafter, an optical element for displacing the focus positions of recording light and reproducing light in the optical axis direction is driven to pull the recording light and the reproducing light onto a targeted recording layer.

    摘要: An optical pickup device includes: a first light source for emitting recording laser light; a second light source for emitting reproducing laser light having a wavelength different from a wavelength of the recording laser light; an objective lens for converging the recording laser light and the reproducing laser light. A quarter wavelength plate is disposed between the first light source and the second light source, and the objective lens. A wavelength-selective polarized beam splitter is disposed between the quarter wavelength plate, and the first light source and the second light source. The reproducing laser light alone out of the recording laser light and the reproducing laser light reflected on recording medium is guided to a photodetector.
