When the objective lens is displaced in the focusing direction, the amplitude value of the focusing error signal detected just after leaving the focal position of a given first recording layer and the amplitude value of the focusing error signal detected just before passing through the focal position of a given second recording layer other than the first recording layer are measured with a particular spherical aberration, the amplitude ratio of amplitude values is calculated, the difference between spherical aberration and the optimal spherical aberration for the second recording layer is approximated as a function of the amplitude ratio, the optimal spherical aberration is calculated on the basis of this approximation, and the spherical aberration is set. | 2013-02-21 |
20130044577 | OPTICAL DISK PLAYBACK DEVICE WITH PRESCAN FUNCTIONALITY FOR EARLY DETECTION OF SURFACE IMPERFECTIONS - An optical disk playback device comprises first and second lasers, an optical assembly, first and second optical detectors, and controller circuitry coupled to the optical detectors. The optical assembly is configured to direct incident light from the first and second lasers so as to form respective leading and trailing scanning spots on a surface of an optical disk, and is further configured to direct corresponding reflected light from the leading and trailing scanning spots on the surface of the optical disk to respective ones of the optical detectors. The controller circuitry is configured to identify a surface imperfection of the optical disk by processing the reflected light associated with the leading scanning spot prior to the trailing scanning spot reaching that surface imperfection. | 2013-02-21 |
