In a machine main unit 1, the execution order of actions of all characters is calculated and the calculated execution order is displayed on a screen. A server, using a seed value shared with a client device, generates a tag stream according to a byte-string algorithm. This facilitates the fabrication of containers with textured surface. Due to the cooling, molecules are uniformly aligned for their early alignment state. The liquid drawn out from the liquid container is fed back into the liquid supply tank. The reflectance Rc of the disk with respect to light with a wavelength of 380 nm to 430 nm, when the recording layer is in a crystalline state, is lower than the reflectance Ra of the disk when the recording layer is in an amorphous state.
