An information recording medium and an optical recording system allow target information to be displayed without requiring changes in hardware or physical specifications. The pad has outward facing dihedral sanding surfaces having an outer dihedral angle of two hundred seventy degrees. At some point in the polymerization prior to the completion of the addition of the conjugated diene to the polymer, the microstructure control agent can be deactivated, either partially or completely, resulting in a polymer or copolymer block having a region of less branching adjacent to a region of more branching. Thus, an electric field is concentrated at the edge portion to induce a corona discharge on and around the entire blade ring. The nanoelement may have the conductance thereof controlled by means of the gate, such that the nanoelement forms a channel region of the field effect transistor. Then, the lower surface of the top flap is attached to the underlying bottom flap.
