Abstract: The present invention relates to a high-density disk (20) 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 is structured such that, wherein a recording layer having high-density pit patterns is offset from a center plane of disk thickness, both sides of a clamping zone bisected by the center plane have differing thicknesses (P1,P2). One or both sides may protrude from surface of the disk recording medium, or one side of the clamping zone may protrude from the surface while the other side is indented below the surface.

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.
