    • A method of self servo-writing servo information to a plurality of disk surfaces in a disk drive that includes writing servo information to a plurality of disk surfaces in a first direction, writing servo information to a plurality of disk surfaces in a second direction, and determining an amount of overlap to be written on a reference surface with the reference head that will produce an overlap of servo information on each of the surfaces in the disk drive to which servo information is to be written. The method also includes switching to different tables when seeking across the overlap or border areas.
    • 一种将伺服信息自伺服写入磁盘驱动器中的多个盘表面的方法,包括将伺服信息沿第一方向写入多个盘表面,将伺服信息以第二方向写入多个盘表面,以及 确定要在参考表面上写入的重叠量,该参考头在伺服信息要被写入的盘驱动器中的每个表面上产生伺服信息的重叠。 该方法还包括当跨越重叠或边界区域时,切换到不同的表。

    • 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.
    • 根据本发明的方法可以包括通过定位打印到盘的参考表面的一个或多个标记区来确定头沿着笔划的位置。 可以将一个或多个标记区域打印到参考表面的一部分,作为可以进一步包括多个人字纹的模板图案的一个或多个脉冲。 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。 当脉冲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。 通过沿着行程移动头部,可以检测到标记区域边缘并确定总位置。 可以通过测量位于与边缘基本相同的径向位置处的人字形的相位来确定小数位置。
