Abstract
This paper applies the modified adaptive feedforward compensation (AFC) scheme to the dual stage servo system for the cancellation of repeatable runout (RRO) and nonrepeatable runout (NRRO). It shows that runout can be effectively compensated or attenuated by assigning runout components to VCM actuator and microactuator properly
