ABSTRACT:
A controller of an optical disk device includes: a first sub-controller, a second sub-controller and a third sub-controller. The first sub-controller includes serially connected a first lead-lag filter and a first low pass filter. The second sub-controller includes a second lead-lag filter and a second low pass filter that are serially connected. The third sub-controller includes serially connected a second lead-lag filter, a third low pass filter and a extra lead-lag filter. A parameter calibrating apparatus and method for the controller is also disclosed.
