摘要:
Update processing and the like of an index file relating to change of a hierarchical structure is performed. The index file is recorded in a recording medium with content files. The index file is generated based on attribute information of content files and folders including the content files. Content files and folders form a hierarchical structure in which the folders are in an upper hierarchy. In the index file, a prescribed number of entries (management information areas) corresponding to content files and folders, respectively, are provided. Second index information indicating second entries corresponding to folders or content files positioned in a lower hierarchy of folders in the upper hierarchy is provided at first entries corresponding to folders in the upper hierarchy in a list format. First index information indicating the first entries is provided at the second entries.

Content files and an index file for managing the content files are recorded in a recording medium. The index file includes, for example, a text file FTX, a thumbnail picture file FTH, and a property file FP. The files each have continuous fixed-length slots. The fixed-length slots are each managed by a slot number (index information) indicative of the order of arrangement thereof. Each file has a predetermined number of management information areas including one or a plurality of continuous fixed-length slots. The management information areas are identified by the index information of the first fixed-length slot. A predetermined entry has a slot number for identifying another entry. The data on the other entry can be acquired by detecting the location of the other entry on the index file.

[Problem] To easily determine the matching/mismatching between the content and index files recorded on a recording medium when turning on power.[Means for Resolution] On a recording medium 2, there are recorded content files and an index file. The index file is constituted by attribute information of the content files (title text data, thumbnail-image data or the like). In the case of changing (recording or deleting) the content file, the index file is updated after the change. A computer 4 sets up, in a nonvolatile memory 15, status information indicative of being in a predetermined process stage, in the predetermined process stage from a start of changing the content file to a termination of updating the index file. The computer 4, at turning on power, determines the matching/mismatching between the content and index files recorded on the recording medium 2 by utilizing the status information, thus repairing the index file as required.

摘要:
An information recording apparatus recording contents on a recording medium and managing the contents by using a content management file includes a control unit that checks a recording state of the recording medium loaded in the information recording apparatus to determine how to set up the content management file to be recorded on the recording medium and recording means for recording the content management file on the recording medium. The control unit determines the file setup of the content management file on the basis of the recording capacity of an area where the contents can be recorded on the recording medium. The recording means records the content management file in accordance with the file setup on the recording medium.
