ABSTRACT:
An optical disk device includes a controller and a parameter calibrating apparatus. The controller includes: a first sub-controller, a second sub-controller and a third sub-controller. The first sub-controller, a second sub-controller in series with the first sub-controller and a third sub-controller in parallel with the combination of the first sub-controller and second sub-controller are used for filtering and passing low-frequency components the input signal respectively. The parameter calibrating apparatus is used for evaluating a performance of the controller.
