Abstract: L'invention concerne un procédé et un système permettant d'assurer le traitement de fichiers en continu au moyen d'une unité de disque (100). On utilise à cet effet plusieurs pistes en spirale sur un disque, en écrivant les données sur lesdites pistes (604). Il est possible d'écrire les données en continu sur les pistes, sans retard pour le passage d'une piste à l'autre. Le système qui permet une telle opération repose sur le traitement en continu des fichiers vidéo, c'est-à-dire sur l'incorporation en continu des données à des fichiers en spirale d'une longueur physique quelconque, sur une unité de disque. On peut créer des sessions multiples de traitement en continu sur le disque sans modifications au niveau de l'utilisateur. Par ailleurs, le système peut supprimer ou sauvegarder des sessions partielles, et réattribuer de l'espace tampon de traitement en continu sans commandes de l'utilisateur. Le format de disque correspondant à cette technologie permet de disposer d'espace libre sur le disque pour les fichiers sauvegardés ou les sessions de traitement en continu, moyennant quoi on utilise la capacité de stockage avec une efficacité accrue.
