Abstract: The present invention relates to a high-density disk that is structured to prevent a collision of an optical pickup's objective lens with the high-density disk if the disk is placed upside down in a disk device that is able to record and reproduce signals to/from the high-density disk. A high-density disk recording medium according to the present invention has a reflecting thin film or label (601), formed on a surface opposite to a recording surface, to block a beam incident to an inserted disk not to travel up to a lead-in area, which a disk device tries to read first when a disk is placed, in the event that the inserted disk has been misplaced upside down.
