          Appeal No. 97-0260                                                          
          Application 08/287,477                                                      


          for moving transducer means relative to the data storage media              
          for reading and writing data to the data storage media, said                
          method comprising the steps of:                                             
               rotating said data storage media using the drive motor;                



               using said transducer means, writing servo information on              
          the data storage media at a first portion of the data storage               
          media using timing information developed without requiring the              
          use of a clock track;                                                       
               using said actuator and transducer means, moving offset                
          from said last written servo information and detecting said                 
          written servo information until said detected servo signal                  
          equals a predetermined value;                                               
               developing timing information from said last written                   
          servo information;                                                          
               using said transducer means, writing servo information on              
          said data storage media responsive to said detected servo                   
          signal equal to said predetermined value using said timing                  
          information developed from said last written servo information              
          without requiring the use of a clock track; and                             
               sequentially repeating said moving, developing timing                  
          information from said last written servo information and                    
          writing steps until a second portion of the data storage media              
          is reached.
