In executing a variety of processing operations for contents data, such as reproducing the contents data, the time until booting the application to enable the operations is shortened. A database file for management of contents data is stored in a hard disc drive and the data for hard disc contents controller (hdcc) processing, formulated on the basis of the database (a data image of the file for hdcc processing) is then saved. Using this data for hdcc processing, the application executes the required processing for the contents data. If, depending on the results of the processing by the application, the registration processing for the database becomes needed, the registration processing for the data for hdcc processing is necessarily executed. By so doing, the data for hdcc processing is kept synchronized with the database file at all times.
