摘要： An optical pickup apparatus includes: a first light source; a second light source; a third light source; an objective lens; a coupling lens; a light flux splitter; and a light-receiving element. The coupling lens is formed of two or more lenses in two or more groups, and at least one group of the lenses forming the coupling lens is arranged movably along an optical axis of the coupling lens. The each of the first to third light source and a light-receiving portion in the light-receiving element is optically conjugate each other through an information recording surface of the information recording medium when at least one group of the lenses in the coupling lens is positioned at the predefined position.

摘要： An optical pickup device includes an objective optical element through which light fluxes respectively with wavelengths λ1, λ2 and λ3 pass and a divergent angle-converting element that causes light fluxes respectively with wavelengths λ1, λ2 and λ3 pass through and causes at least q light flux with wavelength λ1 to emerge as a parallel light. A position of the divergent angle-converting element in the optical axis direction varies in the case of using the optical pickup apparatus depending on the occasion when a light flux with wavelength λ1 or λ2 passes through or on the occasion when a light flux with wavelength λ3 passes through.
