摘要： Methods in accordance with the present invention can include determining a position of a head along a stroke by locating one or more marker-zones printed to a reference surface of a disk. The one or more marker-zones can be printed to a portion of the reference surface as one or more pulses from a template pattern that can further comprise a plurality of chevrons. In one embodiment, each pulse can trace the motion of the stroke along at least a portion of the radius of the reference surface. A pulse can identify a marker-zone edge when the pulse disappears at some radius from the center of the disk. By moving the head along the stroke, the marker-zone edge can be detected and a gross position determined. A fractional position can be determined by measuring a phase of a chevron located at substantially the same radial location as the edge.

摘要： Template patterns in accordance with the present invention can include one or more maker-zones printed to a reference surface of a disk for determining gross-position along a stroke of a read head connected with a rotary actuator. The one or more marker-zones can be printed or otherwise written to a portion of the reference surfaces as one or more pulses. In one embodiment, each pulse can trace the motion of the stroke along at least a portion of the radius of the reference surface. A pulse can identify a marker-zone edge when a di-bit (a transition pair representing a pulse) disappears at some radius from center of the disk. At a radius closer to the center of the disk, the di-bit can abruptly reappear so that the pulse is continued. The interruption in the radial continuity of the magnetized pulse defines the marker-zone and can be any length.

摘要： A two-step self-servowriting process first writes an intermediate pattern based on a reference pattern, and then writes a final pattern based on the intermediate pattern, wherein the reference pattern can be a printed media or a spiral pattern. Such an approach can be utilized to reduce the noise/runout, eliminate timing eccentricity, and increase the sample rate of the final pattern. 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.

摘要： The amount of position error written into a servo burst pattern can be reduced by using additional media revolutions to write the pattern. Where the edges of two servo bursts are used to define a position on the media, trimming the first burst and writing the second burst on separate revolutions of the media will result in a different amount of position error being written into each burst. The end result will be a reduction in the overall error in position information. In order to further reduce the position error given by a burst pair, each burst also can be trimmed and/or written in multiple passes. Additional bursts can also be written, such as for each data track centerline. The overall error in position should decrease as the number of passes used to write a burst pair increases. Also, additional bursts can be written in separate passes in order to further reduce position error while avoiding coherence concerns. 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.
摘要翻译：通过使用额外的介质转数来写入图案，可以减少写入伺服突发图案的位置误差量。在两个伺服脉冲串的边缘用于定义介质上的位置的情况下，修剪第一个脉冲串并将第二个脉冲串写入介质的分开的转数将导致不同量的位置误差被写入每个脉冲串。最终结果将是减少位置信息的总体错误。为了进一步减少由突发对给出的位置误差，每个突发也可以被多次修剪和/或写入。也可以写入附加的脉冲串，例如对于每个数据轨道中心线。随着用于写入突发对的通过次数增加，位置的总体误差将减小。而且，为了进一步减少位置误差同时避免一致性问题，可以单独传递附加的脉冲串。本说明书不是对本发明的完整描述或限制本发明的范围。本发明的其它特征，方面和目的可以通过对说明书，附图和权利要求的评述来获得。

摘要： Embodiments of the present invention determine the offset of a first burst of a burst pair from a centerline. This can be used to determine the desired offset position for a second burst of the burst pair. The target signal to provided the data storage unit for writing the second burst can take into account the transfer function of the controller and the physical plant so as to more accurately write at the desired offset position.

摘要： Systems are provided for improving servo-demodulation robustness, especially when used with a disk having zone bit recorded servo wedges. The systems include a first servo demodulator adapted to search for a servo address mark (SAM) pattern, within a servo wedge, at a first nominal frequency useful for searching for the SAM pattern if the servo wedge is within a first zone. The systems also include a second servo demodulator adapted to search for the SAM pattern, within the same servo wedge, at a second nominal frequency useful for searching for the SAM pattern if the servo wedge is within the second zone. A microprocessor can then determine which of the first and second zones a head is reading, based at least in part on which of the first and second demodulators detects the SAM pattern.
