摘要： An objective lens optical system focuses a light beam with a wavelength λ1 on an information recording surface of a first optical recording medium including a transparent substrate with a thickness t1, a light beam with the wavelength λ1 on an information recording surface of a second optical recording medium including a transparent substrate with a thickness t2, and a light beam with a wavelength λ3 on an information recording surface of a third optical recording medium including a transparent substrate with a thickness t3, by using a refraction action. Sectioning the area of the objective lens optical system is applied to a compatible technique for the same wavelengths, and generating an aberration for canceling a chromatic aberration caused by a difference in wavelength λ of the light beam is applied to a compatible technique for different wavelengths.

摘要： There is provided an optical pickup system which includes a first light source emitting first light having a wavelength λ1, a second light source emitting second light having a wavelength λ2 longer than the wavelength λ1, a third light source emitting third light having a wavelength λ3 longer than the wavelength λ2, and an objective lens focusing the first light on an information recording surface of a first optical recording medium, focusing the second light on an information recording surface of a second optical recording medium, and focusing the third light on an information recording surface of a third optical recording medium. In the optical pickup system, at least one lens surface of the objective lens is divided into a plurality of concentric sections with an optical axis, having a step at each boundary between the sections, each of the sections has a different aspherical shape and m1>m2>0 and −0.060≦m3≦−0.020 are satisfied where an imaging magnification at the first light is m1, an imaging magnification at the second light is m2, and an imaging magnification at the third light is m3 in the objective lens. This enables a decrease in aberration at the first light and the second light and an increase in object distance at the third light. Further, this step enables the shared use of a photodetector for detecting the first light and a photodetector for detecting the second light.

摘要： An information-recording medium of write once or rewritable type designed to have narrow tracks is provided, in which the wobble signal amplitude is scarcely fluctuated by crosstalk. The medium includes recording tracks formed in a spiral form and meandering at a predetermined wobble cycle T, and a plurality of zones constituting each of the recording tracks, each of the zones having a principal area formed to have a predetermined wobble phase. A relationship of T>80b holds between the wobble cycle T and a channel bit length b of recording data. The wobble phase of one of the recording tracks is adjusted so that an average phase difference d is d>π/2 between the wobble phase in the principal area in the zone and a wobble phase of an area in the recording track disposed adjacently on an inner circumferential side or an outer circumferential side of the principal area, in relation to all of the recording tracks disposed adjacently in the radial direction.
