Abstract

L'invention concerne un nouveau système d'application d'un support enregistré, par exemple un disque compact EXTRA, enregistré en multisession sur une machine à sous. Ce système permet à cette machine à sous de reproduire de manière préférentielle des données ROM avant un disque compact DA, ce qui confère à cette machine une certaine avance par rapport aux machines traditionnelles. Cette machine à sous peut en outre être utilisée comme une machine complexe, sur laquelle des disques compacts ROM, des disques compacts musicaux, et des disques compacts EXTRA peuvent être utilisés. Cette machine est donc dotée d'une grande polyvalence et peut être utilisée par une large gamme d'utilisateurs, quel que soit leur âge ou leur sexe. Un logo ordinaire est en outre imprimé sur un disque compact ROM spécialisé, et un logo spécial sur un disque compact EXTRA. Les informations relatives aux données vidéo correspondant au logo et préalablement mémorisées étant affichées de manière sélective, l'utilisateur peut confirmer le type de disque compact chargé.
