    摘要： Before each content file is recorded first to a recording medium, a flag indicating a recording state of a content file is generated corresponding to a physical area where an index file can be continuously recorded. An index file is generated which associates attribute information with the generated flag added thereto with real data of each content file, and the generated index file is recorded to the recording medium. Since fragmentation of the physical area where the index file is recorded is restrained to a minimum level, a high-speed reading operation is realized.

    摘要： The present invention relates to a file management technique using indexes, wherein retrieval results and conditions for retrieval are recorded and stored on an entry for a virtual folder on the index for efficient later use. By this feature, objects for retrieval can be refined by using the recorded retrieval results, so that the processing for retrieval can substantially be simplified.

    摘要： A recording apparatus such as an optical disk and a file management method are disclosed by which, where an index file is formed from groups of data wherein extract information is collected for different types and one of the groups of data is used to collectively manage the other groups of data, a process relating to deletion or addition of extract information can be executed simply, easily, and with certainty. In each of slots of a property entry, information representing whether the slot is valid or invalid and information representative of a relationship to different slots to which extract information relating to the same file is allocated are recorded, and a combination of the slots in which the extract information of the one file is allocated is managed with the property entry.
