Abstract

The present invention provides a method of determining a distance for moving an optical pick-up from a current track to a target track based on a distance from an exact single track width formed on an optical disc. According to the present invention, a method of determining a single track width of an optical disc by an optical pick-up includes the steps of a) calculating a number of tracks crossed by the pick-up using a detection of an initial track position information of an initial track when performing an initial loading of the disc, and track position information of a predetermined track located away the predetermined distance form the initial track; and b) calculating a single track width depending on the predetermined distance and the calculated number of tracks to be crossed by the pick-up. In the present invention, the access time of various optical discs is identical regardless of the size of a single track width of an optical disc.
