摘要： A light source emits light with a first wavelength and light with a second wavelength longer than the first wavelength toward an optical disk from adjacent positions. An optical receiver detects light reflected from the optical disk. An astigmatism-generating element generates light used for focus control in a condition where a focusing position on one of two perpendicular cross sections including an optical axis of the light reflected from the optical disk is located ahead of the optical receiver and a focusing position on the other cross section is located behind the optical receiver are included. The astigmatism-generating element is a Fresnel mirror configured to include a plurality of reflecting mirrors. A level difference between the reflecting mirrors adjacent to each other is distributed in a range from a depth of substantially (natural number/2) times the first wavelength to (natural number/2) times the second wavelength.

摘要： In an optical pickup, light, emitted from a light-emitting element, is transmitted through a first beam splitter film with polarization selectivity, and a zero-order diffraction beam and two (.+-.) first order diffraction beams are produced. These beams are applied in a condensed manner to an optical disk through a condensing element, and the return light beam from the optical disk is fed to a photodetector through a second beam splitter film with polarization selectivity, thereby effecting the recording and reproduction of information, the tracking and the focusing. A diffusion angle conversion hologram is provided between the light-emitting element and the first beam splitter film, and with respect to the diffusion angle conversion hologram, the relation between the diffusion angle of the incident beam and the diffusion angle of the outgoing beam is specified. With this arrangement, the light to be incident on the condensing element can have an ideal spherical wave free from a wave aberration, so that an image spot on the optical disk can be condensed into a diffraction limit, and besides by correcting the phase of the beam, a RF signal with a high C/N ratio, a stable focus error signal and a stable track signal are detected.
