ABSTRACT:
An apparatus and a method determine an area of an optical disc in which an inner area and an outer area of the optical disc having an absolute time of 99 minutes are distinguished from each other by referring to a number of ATIP syncs. The method includes counting the number of ATIP syncs for one rotation of the optical disc at a current position of a pickup when ATIP information recorded on the optical disc indicates that the pickup is currently present in an area of the optical disk that is greater than or equal to 95 minutes; and determining the current position of the pickup by comparing the number of counted ATIP syncs with a reference number of ATIP syncs. Accordingly, time spent determining the area of an optical disc and accessing the optical disc is reduced.
