摘要： 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.

摘要： An optical disc device (2) includes: an optical pickup (4) including a first laser light source (10) that emits laser light, an objective lens (24) that focuses the laser light emitted from the first laser light source (10) onto an optical disc (8), and a light receiving element (30) that receives reflected light from the optical disc (8), and performs photoelectric conversion on the reflected light received to output a received-light signal; an FS signal generator (54) that generates an FS signal indicating the light amount of the reflected light from the optical disc (8), based on the received-light signal from the light receiving element (30); and a dirt determiner (56) that determines that dirt is present in the optical pickup (4), when the peak level of the FS signal is less than a dirt determination threshold, and controls the light receiving element (30) to increase the peak level of the received-light signal from the light receiving element (30).

摘要： In a multilayer optical disc having information layers conforming to a plurality of different optical disc standards, because the type of each information layer is not recorded in the other information layers, in read and write operations by a compatible optical disc device conforming to a plurality of optical disc standards, every time the information layer being accessed changes, it has been necessary to read the type of the information layer and select a method of generating a tracking error signal adapted to the type of information layer, so access has taken time. In order to solve the above problem, in the optical multilayer disc according to the present invention, having information layers conforming to a plurality of different optical disc standards, in an area in one of the information layers, information about the other information layers is recorded. The time required to access the other information layers can be reduced by using this information to select a tracking error signal generating method.
