SOLUTION: The file name of a resource file is set to, e.g., "CCdannn. RCO", the resource file is indicated by an extension "RCO", a language attribute is indicated by CC, the file of a default language is indicated by d, and the aspect ratio of an assumed display device is indicated by a. The symbol nnn is an identification number. When reproduction from the head of contents is instructed, the research file of the language attribute matched with the set language of a player is searched. If present, the file is selected. If not present, the file of the default language is selected. When the two files are selected, the file is selected, based on the aspect ratio. As the initial selection of the resource file is automatically executed, the contents and the resource file are independently recorded, and the menu screen having high degree of freedom or the like is easily manufactured.
