    摘要： A brake disc is provided capable of effectively reducing the generation of noise such as brake noise by making specifications relating to lightening holes different from each other between two brake disc plates. In the brake disc, two brake disc plates are laminated so as to slide on each other by vibration during braking, and specifications relating to one or more selected from lightening holes, plate thickness, diameter, and warpage are made different from each other between the brake disc plates. In addition, lightening holes are formed on at least one of the brake disc plates, and one or more specifications selected from the number of lightening holes, the shapes of the lightening holes, the sizes of the lightening holes, and the arrangement positions of the lightening holes are made different from each other between the brake disc plates.

    摘要： There is provided a new medium structure to record a bar code for copyright protection or the like in an optical information recording medium capable of recording and reproducing information by a laser with respect to a dye. When a laser beam 30 is irradiated and an optical disc 10 is rotation in the direction of an arrow F, the dye of a recording layer is decomposed, a mark piece MA of a bar code 20 is formed, and a substrate is deformed by heat generated by the dye decomposition. Next, the position of the laser beam 30 is shifted to a position where a part overlaps with the mark piece MA, and when the optical disc is similarly rotated in the direction of the arrow F, a mark piece MB is formed to overlap with the mark piece MA. The above processing is repeated, so that the length of a bar is sequentially lengthened, and the bar code with a length along the standard is formed.
