    • An apparatus detects the number of tracks traversed on an optical disk. The apparatus includes a differentiation part for differentiating an output signal of a bandpass filter provided on an adjacent stage which eliminates a low DC component, a high frequency component and noise of an inputted modulation signal. A sample trigger generating circuit generates top and bottom signals in response to a data signal outputted through the differentiation part and a signal outputted through a comparator. A top hold part and a bottom hold part holds the data signal at top and bottom. A subtraction part performs a subtraction to obtain a difference between the top and bottom signals outputted from the top and bottom hold parts, thereby resulting in counting the number of the tracks traversed, while increasing a jumping speed required for a detection of the number of the tracks traversed.

    • An apparatus and method for approaching a focusing region are provided. The apparatus for approaching the focusing region includes a focus error detector, a signal envelope detector, a focusing region detector, a pulse generator for generating search pulses, a time counter, an offset generator, an adder, an actuator driver and a controller. The apparatus approaches the focusing region based on the generating search pulses, which are output in response to a signal generated by the signal envelope detector and a signal output by the focusing region detector. When a subsequent approach to the focusing region is made after finishing a first approach to the focusing region, the actuator is controlled by adding the search pulses to an offset voltage calculated when the first approach to the focusing region was performed to quickly position the object lens in the focusing region.
