CA 2400870

When one recording medium is accessed from a multiple number of applications, the medium is usually divided into multiple areas. If this area division is performed and managed by partitioning, it is difficult to change the size of the partitions. Therefore, there has been the problem that the recording medium can not be used effectively. The recording medium is divided into multiple areas, and for each area, dummy data is written into the blank space in the area so that dummy data can only be overwritten using a particular application or with a file of a particular type. This configuration makes it easy to divide the medium into multiple areas and change the size of the areas.

De manière générale, un support d'enregistrement d'informations accessible par une pluralité d'applications est divisé en une pluralité de zones. Lorsque des segments sont utilisés en vue de contrôler cette division en zones, il est difficile de modifier la taille des segments empêchant une utilisation efficace du support d'enregistrement. On divise un support d'enregistrement en une pluralité de zones, et on inscrit dans une partie non utilisée dans chaque zone de données provisoires pouvant être recouvertes uniquement par une application spécifique ou un fichier spécifique, permettant ainsi une division aisée en une pluralité de zones et des modifications de taille.
