<p>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.</p> |
