Abstract

An application of digital servo control on a high-performance voice coil motor positioning system in hard disk drive is discussed. Modern digital control theory is used in servo algorithm design, and the servo algorithm is implemented by a high-speed microprocessor, OES 22040 model. The experimental results show the excellent properties in time domain and frequency domain.
