An information recording medium manufacturing method is provided in which a resin material can be reliably cured even when a light-transmitting stamper is used repeatedly. Communication between the host computer and the RF terminals is achieved by using the network of intermediate base stations to transmit the data. A heating arrangement heats the upstream portion of the stationary die to prevent the molten metal from solidifying within the casting channel at the upstream portion, thereby allowing the molten metal to fill the casting channel. First, before measuring quality, the tool normalizes the block to account for variation in block sizes. Ideally, the hollow body is a tube made of a material or mixture of materials that is transparent to rays in the optically visible wavelength range, in the infrared range, andor in the ultraviolet range, wherein the material is at least partially transparent to said rays.
