Title
(EN) FILING SYSTEM FOR MANAGING RECORDING AND RETRIEVING OF INFORMATION FILES
(FR) SYTEME DE CLASSEMENT POUR GERER L'ENREGISTREMENT ET L'EXTRACTION DE FICHIERS D'INFORMATIONS
Abstract
(EN)
A filing system is disclosed for managing recording and retrieving of information files on a record carrier of a rewritable type, which have a limited number of overwrites, such as CD-Erasable comprising a phase-change recording layer. The system comprises means for generating non-file and file items comprising management information and means for assigning areas on the record carrier for recording the items, the management information comprising references indicative for the areas, said items comprising a least one item of a first type to be recorded on a predetermined area (e.g. a Primary Volume Descriptor as in ISO 9660) and items of a second type to be recorded on variable areas (e.g. a Path Table and Directory Files). To restrict the number of overwrites, the means for assigning areas are arranged for assigning areas for items of the second type in such a way, that in operational use updated versions of items of the second type are preferably assigned the same area as the original version of the respective item.

L'invention concerne un système de classement pour gérer l'enregistrement et l'extraction de fichiers d'informations d'un support d'un type pouvant être re-écrit, et ayant un nombre limité de superpositions d'écriture, tel qu'un CD effaçable, comprenant une couche d'enregistrement par changement de phase. Le système comprend un moyen pour générer des articles non fichiers et des articles fichiers comprenant une information de gestion et un moyen pour attribuer des zones sur le support d'enregistrement pour enregistrer des articles, l'information de gestion comprenant des références indiquant les zones, et ces articles comprenant au moins un article d'un premier type à enregistrer sur une zone prédéterminée (par exemple un descripteur de volume primaire, comme dans ISO 9660) et des articles d'un second type à enregistrer sur des zones variables (par exemple un tableau de trajets et des fichiers répertoires). Pour limiter le nombre de superpositions, le moyen pour attribuer des zones fonctionne pour attribuer des zones à des articles du second type, de manière à ce qu'en service, des versions remises à jour des articles du second type soient, de préférence, attribuées à la même région que la version originelle de l'article respectif.
