          Appeal No. 2006-2321                                                        
          Application No. 10/706,254                                                  

               The disclosed invention relates to the self-servo writing of           
          a hard disk drive (HDD) in which write control bits are                     
          associated with servo pattern data bits to selectively disable or           
          enable a write gate in a HDD write channel, the write gate being            
          disabled or enabled without deenergizing the write channel.  More           
          particularly, from one timing mark to the next, a single write              
          delay is calculated which enables the writing of the next timing            
          mark and portions of the radial pattern and servo pattern between           
          the timing marks.                                                           
               Claim 1 is illustrative of the invention and reads as                  
          follows:                                                                    
               1.  A HDD, comprising:                                                 
               at least one write channel including at least one write                
          gate; and                                                                   
               control circuitry encoding write control bits for                      
          controlling the write gate to selectively enable writing data               
          bits associated with a servo pattern onto at least one disk.
