摘要： In order to provide an optical pickup apparatus that has a relatively simple configuration and that can carry out recording and/or reproduction of information in a s compatible manner for different optical information storage medium, the optical surface of the first objective lens OBJ1 is formed only by a refracting surface, and hence it is possible to form it at a low cost even if it is made of glass. In addition, said first objective lens OBJ1 can be designed by optimizing it for the first light flux with the wavelength λ1 and the protective substrate t1 of said first optical disk OD1. On the other hand, while the second objective lens OBJ2 is used commonly for both the first light flux with a wavelength λ1 and the second light flux with a wavelength λ2, when the protective substrate t2 of the second optical disk OD2 and the protective substrate t3 of the third optical disk OD3 are the same, there is no need to consider the difference in the thickness of the protective substrate, and hence the design is easy and it is possible to produce at a low cost.

摘要： An objective lens for an optical pickup apparatus includes: one optical surface in an aspherical shape including a central area for converging the first and second light fluxes having a first area and the second area, and a peripheral area for converging the first light flux. The central area includes a first diffractive structure. The first diffractive structure faces an outer side of the objective lens in the first area and faces an inner side of the objective lens in the second area. The peripheral area is an optical surface which makes a light flux passing through the peripheral area reach to a position apart from the optical axis on an information recording surface of the second optical information recording medium when the optical pickup apparatus records or reproduces information on the second optical information recording medium using the second light flux.

摘要： An optical system has an optical functional surface including a common region used for conducting information recording and/or reproducing for both of a first optical information recording medium and a second optical information recording medium. The common region comprises a refractive surface of an imaginary basic aspherical surface and a optical path difference providing structure in which plural ring-shapes zones are separated around the center of an optical axis and neighboring ring-shaped zones are displaced to each other in a direction of an optical axis so as to cause an optical path difference obtained by multiplying a predetermined wavelength λs (λ1

摘要： An optical pickup apparatus for information recording and/or reproduction on different optical information recording media with compatibility among these media, the optical surface of a first objective lens and the optical surface of a second objective lens are formed only of a refractive surface. The second objective lens is used in common for the first light flux with a wavelength of λ1 and the second light flux with a wavelength of λ2, but in the case where the protective substrate t2 of the second optical information recording medium and the protective substrate t3 of the third optical information recording medium are the same, it is not necessary to take the difference in thickness of the protective substrate into consideration. Chromatic aberration based on the difference in wavelength between the first light flux and the second light flux can be corrected by displacing the second coupling lens.
