The minor coherence-errors suffered during servowriting of bursts in a phase burst servo pattern may contribute to significant written-in runout of the resulting pattern. Embodiments of the present invention enables the servowriting of both the zig/zag bursts and/or the digital information of the phase burst pattern all in one single revolution so that the common coherence errors of the zig/zag bursts can be canceled during demodulation. Such single pass servowriting of both zig/zag bursts can be accomplished by either using additional phase-adjustment circuitry or by shifting the phase of the write clock to allow servowriting of the bursts and/or digital information all at edges of (different) integer clock cycles. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.
