ABSTRACT:
A method for determining the position of an optic pick-up head and the device of the same are disclosed. The number of frames in certain section of the disk are used to determine the position of the optic pick-up head. The number of frames in inner section of the compact disk is smaller than that in the outer section. The disk is virtually divided into a plurality of sections, and number of frames within each section is defined. As a result, when the optic pick-up head is at a certain frame, the position of the optic pick-up head can be determined the number of frames in the section.
