CONSTITUTION: A first actuator device(30) records data on a recording media or changes a head position to reproduce recoded data. A second actuator device(31) changes a displacement relative with the first actuator device(30) and controls a head position finely. An error detection device detects the difference between a basis position of the recording media and a real position of the head. A first control part(33) outputs signal to drive and control the first actuator device(30) using output of the error detection device. A second control part(34) outputs signal to drive and control the second actuator device(31) according to output of the error detection device. A third control part(35) reads a predetermined control input to drive the first actuator(30) and adds this to the first actuator device(30) together with output of the first control device(33).

Abstract: PURPOSE: A focus jump method of multi-layer disk driver is provided to perform precise focusing of a laser beam from a layer to another layer move by an application of a feedback control concept. CONSTITUTION: A focus jump method of multi-layer disk driver includes following units. When an object lens is decelerated normally, the gradient of a focus error signal become a negative number. If the movement of the object lens is reversed, since the gradient of a focus error signal is change into a negative number, as a result, the movement of the lens can grasp through an examination of the gradient of a focus error signal. At the moment that the movement of the object lens is reversed, since the moving speed of the lens is nearly 0, there is no a problem to start the focus control although the focus error signal has a comparatively large value. The values of PC_START and PC_END for determining the start and deceleration of the position control process may be fixed and preferably may be controlled according to the kinds of disks.
