Abstract

L'objet de la présente invention est de raccourcir le temps d'enregistrement de plusieurs disques optiques. La solution selon la présente invention porte sur une zone d'informations de gestion d'enregistrement disposée sur une couche d'enregistrement d'un disque optique multicouche retiré d'une cartouche de disques pouvant stocker plusieurs disques optiques multicouches, laquelle peut enregistrer, comme informations de gestion d'enregistrement d'une unité de cartouche de disques, les informations de gestion d'enregistrement (CMA) nécessaires à l'enregistrement des plusieurs disques optiques multicouches. Selon l'invention, un dispositif hôte ordonne, au lecteur de disque spécifique où est chargé le disque optique doté de la zone d'informations de gestion d'enregistrement, de lire les informations de gestion d'enregistrement de l'unité de cartouche de disques ; exécute, sur la base des informations de gestion d'enregistrement acquises, une série de traitements d'enregistrement de données d'utilisateur pour les plusieurs lecteurs de disques ; génère de nouvelles informations de gestion d'enregistrement par acquisition d'informations se rapportant aux résultats de traitement de chaque lecteur de disque ; et ordonne au lecteur de disque spécifique d'annexer lesdites nouvelles informations de gestion d'enregistrement à la zone d'informations de gestion d'enregistrement.
