    摘要: In a magnetic disk file head positioning control system, the servo loop controlling the fine positioning of magnetic heads for a particular head track is responsive to a servo error signal. The servo error signal consists of a low pass filtered head position error signal summed with a pseudo velocity signal derived from the same head position error signal.
