An information recording medium that can be rapidly finalized, and a recording/reproducing apparatus and method using the same are provided. In the information recording medium, a prepit is pre-formed in a finalization area. Since the portion that has to be filled with data in finalizing the information recording medium is previously formed as the prepits series in manufacturing the information recording medium, the time necessary to finalize the information recording medium can be shortened, thereby achieving the rapid finalization of the medium.

L'invention concerne un support d'enregistrement d'information qui peut être rapidement finalisé, ainsi qu'un appareil d'enregistrement/de reproduction et un procédé d'utilisation associé. Dans ce support d'enregistrement d'information, un pré-creux est préformé dans une zone de finalisation. Etant donné que la partie à remplir avec des données lors la finalisation du support d'enregistrement d'information est formée, antérieurement, comme les séries de pré-creux dans la fabrication dudit support d'enregistrement d'information, le temps nécessaire pour finaliser ledit support peut être diminué, ce qui permet de parvenir à la finalisation rapide du support.
