In Hard Disk Drives, a digital control system is usually applied because of the dispersively recorded positioning signal on the disk, so, to improve head positioning accuracy, it is necessary to make the sampling frequency high using conventional methods. However, it is very difficult to increase the sampling frequency, because of the decrease in capacity of the Hard Disk Drive. So, to solve this problem, a method of improving a head positioning accuracy without making the sampling frequency high is proposed in this paper. In the proposed method, a control signal to the Voice Coil Motor is changed in the sampling period. Furthermore, by setting both the changing time allocation and the gain of the control signal to the optimum, the phase delay by discretization is improved and stimulation of the resonance mode of the Voice Coil Motor is avoided. The proposed method does not require an alteration to hardware at all, and is easily applicable to massproduction simply by changing the control program. The validity of the proposed method was confirmed by numerical and experimental results using a miniature 2.5-inch Hard Disk Drive.
