A recording apparatus for recording digital information signals on a removable rewritable disc like recording medium has been proposed. The apparatus comprises writing means (21, 22, 25) for recording the digital information signals and control means (20) for controlling the recording. The apparatus is capable of storing first file system data and second file system data addressing user data in a user area (UA) on the medium. The control means (20) are adapted to store only one set of file entries shared by both file systems data. This reduces time and space necessary for handling file system data.

L'invention concerne un appareil d'enregistrement permettant d'enregistrer des signaux d'information numériques sur un support d'enregistrement amovible du type disque réinscriptible. Cet appareil comporte des moyens d'écriture (21, 22, 25) permettant d'enregistrer les signaux d'information numériques, et des moyens de commande (20) permettant de commander l'enregistrement. Ledit appareil est apte à stocker des données du premier système de fichiers et des données du deuxième système de fichiers adressant des données utilisateur dans une zone utilisateur (UA) sur le support. Les moyens de commande (20) sont adaptés pour stocker un seul ensemble d'entrées de fichiers partagées par les données des deux systèmes de fichiers, ce qui permet de réduire le temps et l'espace nécessaires au traitement des données des systèmes de fichiers.
