摘要： Stable tracking control is achieved for an optical recording medium having a plurality of information recording planes. To achieve this, an optical information device comprises a light source for emitting a light beam, a focusing unit for converging the light beam emitted from the light source onto a predetermined information recording plane of an optical recording medium having a plurality of information recording planes, a beam splitting unit for splitting the light beam reflected by the optical recording medium, and a light detection unit having a light receiver that receives the light beam split by the beam splitting unit, for outputting a signal corresponding to the light intensity of the light beams received by the light receiver. A guide groove is formed on at least one of the information recording planes, and the light receiver is entirely disposed within in a map formed on the light detection unit by the light beam reflected by an information recording plane other than the predetermined information recording plane.

摘要： An optical head that is restrained from becoming larger, even if it is used for an optical-information recording medium that includes a plurality of information recording layers. In this optical head, a collimating lens is formed by a concave lens disposed on the side of a light source and a convex lens disposed on the side of an objective lens. A collimating-lens actuator moves the convex lens in a direction where a spherical aberration is cancelled which is generated according to the thickness of a light transmission layer up to an information recording layer of the optical-information recording medium. An aperture stop is provided on the side of the collimating lens with respect to the objective lens, and the aperture stop is located near the focal position of the convex lens on the side of the objective lens.

摘要： An optical disk apparatus according to the present invention includes: a light emission section for emitting laser light; an optical system for irradiating the optical disk medium with the laser light; and an aberration control section for controlling aberration of the laser light. In one embodiment, the aberration control section repeatedly switches between a plurality of aberration setting states in a focus lock-in operation. In another embodiment, the aberration control section simultaneously sets a plurality of aberration setting states in a focus lock-in operation. As a result, a plurality of aberration setting states can be allowed to substantially coexist within a single optical system.
