Information recording medium, information reproducing apparatus and an information reproducing method

One or more points in layers with a plurality of minute denaturation zone surrounding the refractive index different from the optical properties like transparency information is recorded in the information recording medium, information is disclosed attempts to image reproduction is recorded from the microscope, but no studies reproducing apparatus for a general user in a normal living space can be easily reproduced and the recording apparatus. The information recording medium of the present invention, the information reproducing apparatus and an information reproducing method, the reproduction layer to a predetermined recording medium while changing the focal position while moving image imaging using inspection pattern at a predetermined frequency of a recording medium, examined by the moving image a plurality of still images captured resolution obtained, determines whether data for reproducing, on the determined plurality of still images to be synthesized can be used.
