          Appeal No. 1997-0495                                                        
          Application No. 08/399,787                                                  

          proffered no evidence that reflectivities of the type here                  
          claimed would be desirable (or even possible) in Kuroiwa’s                  
          medium.                                                                     
               For the above stated reasons, we cannot sustain the                    
          examiner’s section 103 rejection of claims 1 through 4 as                   
          being unpatentable over Kuroiwa and Chen in view of Yamada.                 
























          reflectivities and consequent temperature problems addressed                
          by Chen have no apparent applicability to the optical                       
          recording medium of Kuroiwa.                                                
                                          7
