          Appeal No. 98-0600                                                          
          Application 08/541,441                                                      

               invention from the prior art.  In making this                          
               evaluation, all facts must be considered.  The                         
               Patent Office [examiner] has the initial duty of                       
               supplying the factual basis for its rejection.  It                     
               may not, because it may doubt that the invention is                    
               patentable, resort to speculation, unfounded                           
               assumptions or hindsight reconstruction to supply                      
               deficiencies in its factual basis. (Emphasis in                        
               original).                                                             
               In this case, the examiner has made several findings                   
          which lack an adequate factual basis in the record.  First,                 
          the                                                                         
          examiner concludes that Figure 1 of Kira shows a recess                     
          between the magnetoresistive sensor 3 and the air bearing                   
          surface located along the side where arrow A is disposed.  But              
          because of the angular view of the illustration, the                        
          appellant’s view is just as plausible that the forward end of               
          sensor element 3 is actually aligned or flush with the air                  
          bearing surface.  The examiner does not point to any                        
          description in the specification which refers to or discusses               
          a recess as is claimed by the appellant, or otherwise                       
          identifies a recess as being illustrated in Figure 1.                       
               Secondly, the examiner finds that in Kira the gap defined              
          by the "alleged" recess is filled with a dielectric material,               
          even though the examiner points to no description or                        

                                          4
