摘要： An optical pickup apparatus to conduct reproducing and/or recording information of an optical information recording medium, comprises a light source to emit a light flux having a wavelength of λ (nm); a converging optical system to converge the light flux emitted from the light source onto a information recording surface of the optical information recording medium, the converging optical system having an objective lens; and an optical detector to receive reflected light from the optical information recording medium. The objective lens is a plastic lens, has a diffracting section on at least one surface thereof and satisfies the following conditional formula: 0.3 ≤ ϕR/ ϕ ≤1,5 where ϕR represents a refracting power of the objective lens on wavelength λ (nm) of the light source and ϕ represents a power of the objective lens in wavelength λ nm of the light source.

The optical pickup apparatus comprises a first light source that emits a first light flux, a second light source that emits a second light flux, a third light source that emits a third light flux, and an objective optical element. The optical surface of the objective optical element has at least two areas of a central area and a peripheral area surrounding the central area, wherein the central area has a first optical path difference giving structure and the peripheral area has a second optical path difference giving structure. The objective optical element focuses the light fluxes passing through its central and peripheral areas on the information recording surfaces of respective prescribed optical discs so that the information can be recorded and/or reproduced. The first optical path difference giving structure is formed by superimposing a first basic structure and a second basic structure having respective predetermined structures on each other.
