Abstract: A rewritable optical disc has a laminate of first and second recording layers with first and second trial write areas respectively. Sections of the first trial write area are sequentially used in an order accorded with a direction from an outer disc edge toward an inner disc edge. Sections of the second trial write area are sequentially used in an order accorded with a direction from the inner disc edge toward the outer disc edge. The distance between an innermost used section of the first trial write area and an outermost used section of the second trial write area is calculated. A decision is made as to whether or not the calculated distance is greater than a threshold value. All the used sections in the first and second trial write areas are subjected to signal erasure when the calculated distance is not greater than the threshold value.
