1.A fast efficient pole disposition method was presented,and,based on it,a state feedback controller was designed for a hard disk drive servo system.
2.The dynamical response of head disk system to a half sine pulse excitation is analyzed by means of numerical method according to the dynamical equations of head disk collision under the shock excitation for the Winchester type hard disk drive.
3.The paper initiates a new conception of magnetic levitated hard disk drive based on force controlling.hard disk.
