This paper introduces a data-based controller design method to compensate for external disturbances in head positioning systems of hard disk drives (HDDs). For increasing a data capacity of HDDs, head-positioning-control system must compensate for any disturbance which worsen positioning accuracy. It is an important design problem how to compensate for external disturbances in the head positioning system. The mathmatical of exteranal disturbances are difficult to identify, therefore, the ideal controller cannot be designed theoritically. In this study, we have proposed the databased controller design method to compensate for the external disturbances in the head positioning systems of HDDs. Experimental results shows the designed controller can compensate for the external disturbances in head positioning systems of HDDs.
