摘要： In a particular embodiment, a storage system is disclosed that includes a discrete track media having a plurality of concentric data tracks to store data and including a respective plurality of non-magnetic regions to separate adjacent data tracks. The non-magnetic regions include encoded position information. The storage system further includes a controller adapted to adjust a position of a read/write head relative to a center of a particular track based on the encoded position information.

摘要： A method and system determines the position of a transducer head based on permanent servo marks in which the width of the permanent servo marks is greater than the width of the data tracks they are used to identify. The method includes receiving readback signals in response to the permanent servo marks arranged as a number of null bursts and generating position error signals with respect to each null burst. Region based information is extracted based on the position error signals, and the region based information is used in conjunction with the position error signals to generate region-based displacement estimates with respect to each null burst. The region-based estimates are then combined to generate a final displacement estimate that describes the estimated distance between a transducer head and the centerline of a desired data track.
摘要翻译：一种方法和系统基于永久伺服标记确定换能器头的位置，其中永久伺服标记的宽度大于其用于识别的数据轨迹的宽度。该方法包括响应于排列为多个零脉冲串的永久伺服标记接收回读信号，并相对于每个零脉冲串产生位置误差信号。基于位置误差信号提取基于区域的信息，并且与位置误差信号一起使用基于区域的信息，以生成关于每个空突发的基于区域的位移估计。然后组合基于区域的估计以产生描述换能器头与期望数据轨道的中心线之间的估计距离的最终位移估计。
