A PC, which is a data-processing apparatus copies a file in a mini disc via a data-recording apparatus. The file is composed of a copyrighted music content accumulated in the HDD of the PC, which have been reproduced from another recording medium such as a CD, a DVD or the like. The data-recording apparatus records the ID specific to the PC in the mini disc. Not only the music file, but also the content ID specific to the content is recorded in the next-generation mini disc used in an embodiment of this invention. The music file, thus backed up, is restored when the device in which the content is to be restored is identical to the PC that has been checked out, or when this device is collated to be identical to the PC. |
