Zusammenfassung:METHODS AND SYSTEMS FOR SELF-SERVOWRITING A DATA STORAGE MEDIUM ARE DISCLOSED, INCLUDING SERVOING TO PROPAGATION BURSTS OF A PROPAGATION PATTERN LOCATED IN TRACKS OTHER THAN AN IMMEDIATELY PRECEDING TRACK. REFERENCE LEVELS USED TO POSITION A RECORDING HEAD ARE ACCORDINGLY KEPT IN A USABLE DYNAMIC RANGE NECESSARY TO KEEP SERVO TRACK SPACING CONSTANT ACROSS THE MEDIUM. THE METHODS AND SYSTEMS ARE DISCLOSED IN CONNECTION WITH A ROTARY ACTUATOR HAVING SPACED READ AND WRITE HEADS. SIMILAR METHODS ARE DISCLOSED FOR WRITTING TRIGGER OR TIMING BURSTS OF THE PROPAGATION PATTERN.
