This paper describes a new H/sub /spl infin// track-following controller design for a magnetic head positioning mechanism in hard disk drives. The proposed controller design scheme is constructed under the conditions of a digital controller, low sampling frequency and no anti-alias filter. The in-phase positioning mechanism is chosen as an example. The… (More)
