In the market for miniature 2.5-inch hard disk drives and smaller sizes, there exists a growing need for faster drives with larger capacities. The demands for the robustness of the head positioning control system are becoming severe.<br>Generally, a high bandwidth servo loop or a feedback control system designed for optimum protection against external disturbance is necessary to realize robust performance. However, a limited servo bandwidth by the resonance of a voice coil motor or the strict estimation of the external disturbance makes it diffcult to realize a robust head control system using the linear feedback controller only.<br>In this paper, a head control system using a sliding mode controller with linear feedback controller is presented. The control method enables to realize the higher robustness and the smaller chattering caused by the sliding mode controller than the conventional feedback controller.<br>The validity of the proposed method is confirmed by the numerical and experimental results in the miniature 2.5inch hard disk drive.
