Abstract:
A method of determining a distance for moving an optical pickup from a first track to a second track on an optical disc, comprising:moving the pick-up to a track located a predetermined distance from an initial track position when performing an initial loading of the disc;detecting a position information corresponding to the track located a predetermined distance from the initial track position;calculating a number of tracks crossed by the pick-up based upon initial position information corresponding to the initial track positions and the position information corresponding to the track located a predetermined distance from the initial track position;calculating a single track width by dividing the predetermined distance by the calculated number of tracks crossed by the pick-up;anddetermining a distance to be moved by the pick-up from a current track to a target track when the microprocessor detects a search mode of a target track during playback of the disc, the distance being determined based on the determined width.
