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.
Lorsqu'un support d'enregistrement est sollicité à partir de multiples applications, ce support est habituellement divisé en zones multiples. Si cette division par zones est effectuée et gérée par partitionnement, il est difficile de modifier la taille des partitions. Par conséquent a surgi le problème selon lequel il n'est pas possible d'utiliser efficacement le support d'enregistrement. Ledit support d'enregistrement est divisé en zones multiples, et pour chaque zone, des données factices sont inscrites dans l'espace en blanc de la zone, de sorte que ces données factices peuvent être seulement recouvertes au moyen d'une application particulière ou avec un fichier de type particulier. Cette configuration facilite la division du support en zones multiples et permet de modifier la taille de ces zones.
