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.
摘要翻译：根据本发明的模板图案可以包括打印到盘的参考表面的一个或多个制造商区域，用于确定沿着与旋转致动器连接的读取头的行程的总位置。可以将一个或多个标记区域作为一个或多个脉冲打印或以其他方式写入参考表面的一部分。在一个实施例中，每个脉冲可以沿着参考表面的半径的至少一部分跟踪行程的运动。当二位（表示脉冲的转换对）从磁盘中心的某个半径消失时，脉冲可以识别标记区域边缘。在靠近盘中心的半径处，二位可以突然重新出现，使脉冲持续。磁化脉冲的径向连续性的中断限定了标记区域，并且可以是任何长度。

摘要： An optimized refresh strategy for increasing bandwidth of an LCD. The present invention results in an LCD suitable for dynamic display of information. In the present invention, a display memory is used to store display data generated by a CPU and to provide that data to an LCD. All data writes to the display memory by the CPU are tracked and rows or columns that contain modified data are tagged. These tags may be "set" by mapping the display memory write addresses to row or column numbers. The tags are examined and mapped back into the display memory addresses and only those rows or columns containing changed data are transferred to the data stream for display. As a result, only the information that is changed in the display memory is sent to the display and the dynamic bandwidth of the display is maximized. The refresh in the present invention can be either row-based or column-based.
