Abstract: Two or more signals are read from two or more respective tracks of a disk drive recording medium using respective two or more read transducers co-located on a slider. The slider is aligned to the two or more tracks in response to the correlation between the two or more signals.

Abstract translation: 使用共同位于滑动器上的相应的两个或更多个读取换能器，从盘驱动器记录介质的两个或更多个相应磁道读取两个或更多个信号。 响应于两个或更多个信号之间的相关性，滑块与两个或更多个轨迹对准。

Abstract: Servo data of one or more tracks of a disk are collected using first and second read transducers co-located on a slider. Redundant portions of the servo data collected by the first and second read transducers are compared, and at least part of the servo data validating or corrected based on comparing the redundant portions.

Abstract: At least three servo burst frequencies are simultaneously detected during a rotation of a disk using a read head. A position of the read head during the rotation is determined based on simultaneously reading at least two of the at least three servo burst frequencies.
