CA 2508454

A method of managing overwrite and a method of recording management information on an optical disc write once can make it possible to perform a logical overwrite on the disc and thus heighten the use efficiency of the disc. The method includes replacement-recording data which is requested to be overwritten in a specified area of the disc where recording is completed in another data area physically separated from the specified area in the disc, and producing and recording management information for reproducing the physically replacement-recorded data.

L'invention porte sur un procédé de gestion d'écrasement et sur un procédé d'enregistrement d'informations de gestion sur un disque optique non réinscriptible permettant d'effectuer une réécriture logique sur le disque tout en augmentant ses capacités. Ledit procédé consiste: à remplacer les données à écraser se trouvant dans une zone spécifique du disque où l'enregistrement est terminé, et à les enregistrer dans une autre zone de données physiquement séparée de ladite zone spécifique, puis à produire et enregistrer les informations de gestion des données remplacées et enregistrées.
