摘要： A compound objective lens, an optical head device, an optical information device, and an information processing device that can inhibit the occurrence of aberration even when a light beam source wavelength shifts from the designed value. A diffraction structure having a sawtooth or stepwise cross section is formed in the region (R10) and region (R20). The height of the sawtooth or stepwise cross section formed in the region (R10) provides a light beam, which has a predetermined wavelength, with a difference in optical path length of N times the predetermined wavelength, as compared with a case of propagation in air. The height of the sawtooth or stepwise cross section formed in the region (R20) provides the light beam, which has the predetermined wavelength, with a difference in optical path length of J times the predetermined wavelength, as compared with a case of propagation in air. At least one of the difference in height between both ends of a boundary band (RB) provided between the region (R10) and the region (R20), and the width of the boundary band (RB) provides the light beam, which has the predetermined wavelength, with a difference in optical path length of (N+J)/2 times (N and J are mutually different natural numbers) the predetermined wavelength, as compared with a case of transmission in air.

摘要： An optical head device includes a light blocking region (7y) which is disposed on a light flux of a reflected light beam resulting from reflection by a recording layer on which a blue light beam is focused, and blocks, when there are at least two recording layers on a blue light beam incident side of the recording layer on which the blue light beam is focused or on a side thereof opposite to the blue light beam incident side, reflected light beams resulting from reflection by the at least two recording layers which are incident on a region in a photodetector (9) where the reflected light beams resulting from the reflection by the at least two recording layers interfere with each other. The light blocking region (7y) is not formed on an optical axis of the reflected light beam resulting from the reflection by the recording layer on which the blue light beam is focused. This configuration allows an improvement in the S/N ratio of a signal outputted from the photodetector.
