          Appeal No. 1998-2499                                                        
          Application No. 08/632,639                                                  


          element having a width between 1/3 and 1/2 of the width of the              
          data cylinder.                                                              


               Since the APA appears to teach away from the claimed                   
          subject matter, the examiner is missing a critical feature of               
          the instant claims (both independent claims 1 and 11 require                
          the read element to have a width between 1/3 and 1/2 of the                 
          width of the data cylinder) which is not provided by any of                 
          the applied references.  Accordingly, no prima facie case of                
          obviousness has been provided.                                              


               Moreover, since APA teaches away from the claimed subject              
          matter, we find no basis for combining Moon and APA.  Further,              
          the examiner has provided no convincing rationale as to why                 
          the skilled artisan would have sought to combine the separate               
          read/write heads of APA with the single head system of Moon.                


               The examiner’s decision rejecting claims 1, 3, 4, 6, 8,                
          11 and 12 under 35 U.S.C. 103 is reversed.                                  


                                      REVERSED                                        
                                          6
