ABSTRACT:
A method for stabilizing track jump of a recording medium by which bumping of an object lens disposed in a sled against the sled's wall can be prevented during a track jump for accessing a desired track on a recording medium, in which tracking is turned off whenever the sled is kicked and the numbers of zero crossing of the track are counted by first turning off the sled, and alternately kicking the tracking and checking the zero crossing, until the zero crossing reaches a predetermined number.
