          Appeal No. 1997-3965                                                        
          Application No. 08/389,069                                                  


          track and increasing the angle between the slider and the                   
          tangent of the track over which the slider is positioned as                 
          the slider moves radially outward from the innermost track.                 
          Further, Kuroda and Ono, as well as Toensing, orient the rails              
          parallel to the longitudinal axis of the slider body.                       
          Therefore, both the longitudinal axis of the slider and the                 
          rails of the slider will be at an angle of zero degrees to the              
          tangent of the innermost track, not an intermediate track.                  
               We agree that the application of the teachings of Kuroda               
          and Ono to Toensing eliminates the angular relationship                     
          between the slider body and the tangent to the intermediate                 
          track.  The issue therefore is whether Yamada provides                      
          motivation for reestablishing the relationship between the                  
          slider body and the tangent to an intermediate track.                       
               Yamada teaches forming the rails at an angle to the                    
          longitudinal axis of the slider body and aligning the slider                
          body and arm parallel to the tangent of a track instead of                  
          aligning the slider body at a skew angle to the track tangent.              
          Then, the apparatus can be formed more easily as the slider                 
          axis can be simply matched with the tangent of the track,                   
          thereby avoiding the difficulty of precisely providing the                  
                                          8
