          Appeal No. 2000-1569                                                        
          Application 08/964,686                                                      


          arguments.  See Id.; In re Hedges, 783 F.2d 1038, 1039, 228 USPQ            
          685, 686 (Fed. Cir. 1986); In re Piasecki, 745 F.2d 1468, 1472,             
          223 USPQ 785, 788 (Fed. Cir. 1984); and In re Rinehart, 531 F.2d            
          1048, 1052, 189 USPQ 143, 147 (CCPA 1976).  Only those arguments            
          actually made by appellants have been considered in this                    
          decision.  Arguments which appellants could have made but chose             
          not to make in the brief have not been considered [see 37 CFR               
          § 1.192(a)].                                                                
          With respect to representative claim 1, the examiner                        
          finds that Kijima and Rea each teaches a magnetic disk which uses           
          a chemical attacking agent for softening the substrate material             
          and colloidal particles for removing the softened substrate                 
          material.  The examiner notes that Kijima and Rea are silent as             
          to calculating the surface roughness of the substrate.  The                 
          examiner finds that it would have been obvious to the artisan to            
          calculate the surface roughness in Kijima or Rea with an atomic             
          force microscope as taught in the art [answer, pages 4-7].                  
          Appellants argue that the examiner’s rejection fails to                     
          account for the recitation in all claims that the substrate                 
          material has a surface roughness of less than 4, 3, or 2                    
          Angstroms [brief, page 7].  The examiner responds that the                  


                                          11
