          Appeal No. 1997-4446                                                        
          Application No. 08/278,151                                                  


          relative position error signal of one magnetic head with                    
          respect to one track, stores a control signal indicating the                
          amount of displacement of an actuator corresponding to the one              
          magnetic head, and drives a second actuator according to the                
          control signal to track a second head associated with the                   
          second actuator.  Claims 1 and 25 are illustrative of the                   
          claimed invention, and they read as follows:                                
               1.   A rotary head type magnetic recording/reproduction                
          apparatus having a function of reproducing a main signal from               
          a plurality of tracks having a plurality of pilot signals of                
          different frequencies recorded to be superimposed sequentially              
          on the main signal for every other track, said rotary head                  
          type magnetic recording/reproduction apparatus comprising:                  
               a rotary drum;                                                         
               a plurality of actuators attached on a circumferential                 
          face of said rotary drum with a constant distance                           
          therebetween, each of said plurality of actuators being                     
          displaceable in a track width direction;                                    
               a plurality of magnetic heads attached to said plurality               
          of actuators in a one-to-one correspondence;                                
               means for detecting a relative position error signal of                
          one magnetic head out of said plurality of magnetic heads with              
          respect to one track out of said plurality of tracks according              
          to said pilot signal components included in a signal                        
          reproduced from said one track by said one magnetic head;                   
               first control means for generating a control signal                    
          indicating an amount of displacement of one actuator                        
          corresponding to said one magnetic head out of said plurality               
          of actuators, and for driving said one actuator so that the                 
                                          2
