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： 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.
