摘要： PROBLEM TO BE SOLVED: To provide an optical recording medium having a wobbling amplitude that can improve both of the reproducing signal quality of additional information and data recording/reproducing quality. SOLUTION: In the optical recording medium, the wobbling amplitude of a groove 2 is set in the range of properly securing the reproducing signal quality of additional information (address information or clock information), and in the range of recording/reproducing data well ( the experimentally obtainable range ) by preventing the influence of wobbling. That is, when the numerical aperture of an objective lens is NA and the wavelength of a recording laser beam is λ in the optical recording/reproducing device, the absolute value A of the wobbling amplitude of the groove 2 is set to satisfy 0.0044≤A×NA/λ≤0.0133. Thus, both of the reproducing signal quality of the additional information and data recording/reproducing quality is heightened. COPYRIGHT: (C)2004,JPO

SOLUTION: An optical information recording medium includes a plurality of information recording layers having recording marks having a length shorter than an optical system resolution limit. Information on the information recording layer closest to a reproduction-laser-incident surface can be read by a reproduction laser power lower than reproduction laser power for reading an information recording layer farthest from the reproduction-laser-incident surface. Medium information on the configuration of the medium is recorded near an inner diameter hole. In a reproduction device reproducing the above medium, a reproduction clock to be used for a signal processing circuit based on the medium information is changed depending on whether a normal medium or the super resolution medium is used.
