摘要： Provided is an optical pickup device capable of ensuring the compatibility among three types of optical discs, i.e., BDs, DVDs, and CDs, with a common objective lens and, in addition, capable of ensuring a sufficient working distance for CDs, and also provided are an optical information recording and reproducing device and an objective lens suitable for the optical information recording and reproducing device. On the objective lens, there is arranged a first optical path difference providing structure formed such that: the direction of step differences of a basic structure wherein the diffraction order of a blue-violet laser light flux become an odd order faces toward the opposite direction of the optical axis; the direction of step differences of a basic structure wherein the diffraction order of the blue-violet laser light flux become an even order faces toward the optical axis; and both the basic structures are overlapped together.

摘要： An optical pickup apparatus according to the present invention includes: a first light source for emitting a first light flux; a second light source for emitting a second light flux; a third light source for emitting-a third light flux; and an objective optical element. The objective optical element has an optical surface including at least two areas provided with optical path difference providing structures. The objective optical element converges the first to third light fluxes each passing through the predetermined areas on the objective optical element onto respective information recording surfaces of the first to third optical disks. The optical pickup apparatus provides a wavelength dependency of a spherical aberration so as to correct a change in a spherical aberration due to a refractive index change with a temperature change of the objective optical element.

摘要： An optical pickup apparatus comprises: a first light source; a second light source; a third light source; and an objective optical element. The objective optical element comprises at least two areas comprising first and second optical path difference providing structures. A third light flux from the third light source passing the first optical path difference providing structure forms first and second best focuses. The third light flux passing the objective optical element forms a spot comprising a central spot portion; an intermediate spot portion; and a peripheral spot portion. The central spot portion is used for recording and/or reproducing information for a third optical disk, and the intermediate and peripheral spot portions are not used for recording and/or reproducing information for the third optical disk. The peripheral spot portion is formed on the third optical disk by the third light flux through the second optical path difference providing structure.
