    摘要： In a confocal optical system having a light source 13, a first focusing means 14, a second focusing means 16, an aperture 17, and a detector 18 including a plurality of light reception regions, a position displacement is detected by detecting an intensity distribution of an image caused by a position displacement between a focusing spot of the second focusing means 16 and the aperture 17, by the detector 18. Further, the position displacement is corrected by controlling the aperture position using driving means 19 and control means 20. Also, a position displacement of the aperture 17 in the optical axis direction is detected and corrected on the basis of a change in an output of the detector 18 by oscillating the aperture 17 in the optical axis direction.

    摘要： A confocal optical device and a spherical-aberration correction method reduce the generation of spherical aberration. This confocal optical device includes a drive mechanism which moves a sample board to change the distance between an objective lens and the sample board. A spherical-aberration correction element is disposed between a light source and the objective lens. A reference-position detection section, based on a detection result by a photo-detector, detects the position of the sample board when the focal position of the objective lens coincides with the surface of the sample. A movement-distance derivation section, based on a detection result by the photo-detector, calculates a distance by which the sample board is moved until the focal position of the objective lens coincides with an object to be measured inside of the sample, and derives the depth at which the measured object is located in the sample. A correction control section controls the spherical-aberration correction element according to the inside-sample depth of the measured object.

    摘要： An object of the present invention is to acquire optimum recording characteristics of an optical recoding medium having multiple data layers, with respect to each of the multiple data layers without increasing learning time required for learning a relation between aberration amount and optimum recording compensation with respect to each of the multiple data layers. The present invention includes a wavefront converter which is driven in such a manner as to reduce the aberration amount detected by an aberration detector. An output controller holds learned data as to the relation between the driving amount of the wavefront converter and the output of a light source, and controls the output of the light source based on the driving amount of the wavefront converter and the learned data.

    摘要： An optical head device includes: an optical element collecting light reflected from a reproduction information layer (a target information layer in an optical information recording medium) and light reflected from information layers adjacent to the reproduction information layer at different positions; a light receiving element obtaining a detection signal from the reflected light collected by this optical element; and arithmetic circuitry obtaining a reproduction signal from this detection signal. The light receiving element includes: a first light receiving portion detecting a first detection signal from light containing the light reflected from the reproduction information layer; a second light receiving portion detecting a second detection signal from light reflected from a first adjacent information layer located more distant from the condensing lens than the reproduction information layer; and a third light receiving portion detecting a third detection signal from light reflected from a second adjacent information layer located closer to the condensing lens than the reproduction information layer. The arithmetic circuitry uses constants K and L determined depending on spaces between the reproduction information layer and the adjacent information layers, so as to subtract the K-times second detection signal and the L-times third detection signal from the first detection signal.

    摘要： An information recording medium (21) of the optical information reproduction device of the present invention includes a recording unit (3) capable of recording information three-dimensionally and provided with a track, and information is recorded by forming a plurality of recording marks along the track of the recording unit by a mark length recording method. When the track direction of the recording marks is assumed to be their longitudinal direction and the direction perpendicular to the track direction is assumed to be their lateral direction, with the present invention, for recording marks located substantially in the same plane, the total area of elongated recording marks, whose longitudinal length is greater than their lateral length, is greater than the total area of recording marks having other than elongated shapes. The optical information reproduction device of the present invention includes a first light source (20a) for emitting a reproduction light (22b) having a wavelength λ1, an objective lens (6) for focusing the reproduction light on the recording unit, and a first photodetector (19a) for detecting a reproduction signal from the reflected light from the recording unit. The focused reproduction light includes as its main component a polarized light component that is polarized perpendicular to the track direction. Also, the recording unit has a track pitch of no more than 1.3 times the wavelength λ1 of the reproduction light.
