Spiral servo track writing (SSTW) is the writing method which writes servo information based on spiral pattern. One important factor of SSTW is the setup time of acceleration/deceleration region. In this paper, we design a reference input and electrical spring controller to reduce the setup time. Reference input is used to suppress the resonance excitation caused by fast seeking and settling motion. Current estimator with integral control is employed as the base controller, which compensates the bias force in the SSTW system. However, integral control has a drawback of worsening the setup time with respect to SSTW, so we propose an electrical spring controller to overcome this problem. The performance of the proposed strategy is verified by simulation which shows the setup time is reduced by 36% with electrical spring in combination with the base controller.
