A method for seeking a target position on a multi-layer disc is provided. When a target position seek operation requires a layer jump in an optical disc, a required horizontal movement direction for the optical pick-up is determined. If the optical pickup must move horizontally from the outer circumference to the inner circumference of the disc, the horizontal movement operation is performed first at the current layer, and then a layer jump operation is performed. Because the layer jump operation is performed at the inner circumference of the optical disc, where the optical pickup will not likely encounter a data area which includes location information, a target position seek operation which requires a jump between multiple layers of the disc can be precisely and rapidly performed.
