A recording apparatus for recording digital audio/video 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 performing initialization, formatting and defect management of a rewritable medium. Further, the apparatus is capable of storing data in replacement areas instead of defect areas, which have been determined to be defective according to rules of the defect management. The control means (20) are adapted to re-record data from the replacement areas in the defect areas in order to improve playability of digital audio/video signals stored on the medium.

Appareil d'enregistrement permettant l'enregistrement de signaux audio/vidéo numériques sur un support d'enregistrement du type disque réinscriptible amovible. Cet appareil comporte des moyens d'écriture (21, 22, 25) assurant l'enregistrement des signaux d'informations numériques, et des moyens de commande (20) assurant la commande de l'enregistrement. L'appareil est apte à réaliser l'initialisation, le formatage et la gestion de défauts d'un support réinscriptible. Par ailleurs, l'appareil est apte à mémoriser des données dans des zones de substitution au lieu de zones de défauts dont on a déterminé le caractère défaillant en suivant des règles de gestion de défauts. Les moyens de commande (20) sont adaptés pour réenregistrer les données des zones de substitution dans les zones défaillantes afin d'améliorer la lisibilité des signaux audio/vidéo numériques mémorisés sur le support.
