<p>The disk recording device of the present invention includes a recording means and a file system recording means. The recording means performs recording of an image signal upon a recordable (not rewritable) type optical disk. The file system recording means includes an address information search means and an address information recording means. If the recording of the file system has failed, the address information recording means records the address information in the lead-in region, but does not thus record the address information if it is already recorded in the lead-in region, or the like.
