          Application 08/599,875                                                       

                                    THE PRIOR ART                                      
               The Examiner relies on the following prior art:                         
               Daniels et al. (Daniels)            2,680,239        June 1,

          1994                                                                         
               Kitahara                       5,519,676        May 21,                 
          1996                                                                         
                                   (effective filing date October 11,                  
          1994)                                                                        
               Daniels discloses an apparatus for rapidly selecting a                  
          desired area or point among a group of such areas or points                  
          positioned in a track.  The disk embodiment has a clock pulse                
          track 13 read by a transducer 16, positional data track 14                   
          read by transducer 17, and intelligence track(s) 15 having 10                
          transducers 18, 18', 18", etc., which "may be interprted [sic]               
          as indicating either one or more heads, depending on the                     
          number of tracks involved" (col. 3, lines 69-71).  When it is                
          desired to locate certain areas, positional data is read from                
          track 14 and the difference in position is determined.  "With                
          the difference thus determined, the transducing unit in                      
          closest anticipatory proximity to the area to be selected is                 
          enabled for transducing while the other transducing units                    
          remain unenabled."  Col. 1, lines 40-44.  Thus, Daniels                      
                                        - 4 -
