Abstract

Slow access speed is still the problem to limit applications of rewritable optical disk drives. Dual stage actuators with a coarse and a fine actuator are used in optical disk drives. In this paper, the two-actuator cooperative seek control method, based on time optimal seek control, is presented, and the average seek time is analyzed theoretically.
