Abstract

To reduce the average accessing time of a magneto-optical (MO) disk drive, which is a severe drawback of current products, a newly developed moving-magnet type tracking actuator has been designed and tested. The effort of developing a fast positioning actuator is divided into two parts. One is to develope a new driving mechanism having a fast tracking capability and the other is to adopt an advanced control scheme. In this work, the second effort is mainly addressed using a hybrid control and adaptive model-following control.
