A seeking method of an optical disc drive includes steps of (a) calculating a deviation signal value between a location of a fine actuator and a coarse actuator, (b) judging whether or not the deviation signal value is within a deviation signal threshold interval, (c) outputting a characteristic value to push the coarse actuator if the deviation signal value is not within the deviation signal threshold interval, and (d) jumping to a target track.
