摘要

We propose a method for simultaneously detecting the position and velocity of a magnetic head relative to the target track in a hard-disk drive (HDD) by using a new servo pattern. The position is derived from the phase shift of the burst signal from the pattern, and the velocity is derived from the frequency shift thereof. By applying this method. the sampling rate of the servo system can be reduced to less than 1/2.
