          Application No. 08/399,787                                                  

          . to the recording medium of Kuroiwa” (answer, page 6).  From               
          our perspective, however, the examiner has failed to carry his              
          initial burden of establishing a reason or motivation coupled               
          with a reasonable expectation of success in support of this                 
          proposed addition.  In re O’Farrell, 853 F.2d 894, 903-904, 7               
          USPQ2d 1673, 1680-1681 (Fed. Cir. 1988).                                    
               For example, Chen addresses a temperature problem                      
          exhibited by certain active (i.e., recording) layer materials               
          which exhibit a lower reflectivity in the amorphous and liquid              
          states than in the crystalline state whereby the material                   
          absorbs more light and becomes hotter as it transforms from a               
          crystalline to a liquid phase (e.g., see lines 7 through 27 in              
          column 2).  This problem is avoided by providing an optical                 
          recording media having such an active material layer with a                 
          certain structure including a dielectric layer and a                        
          reflective layer and including certain layer thicknesses such               
          that the reflectivity of the liquid state is higher than of                 
          the crystalline state thereby avoiding the aforementioned                   
          temperature problem.  On this record, there is no basis for                 
          concluding that the recording or active material of Kuroiwa                 
          exhibits the temperature problem addressed and solved by Chen.
