摘要：
Whether an optically writable label surface of an optical disc is suitable for having an image formed thereon is determined. A detectable number of encoder spokes on a control feature area of the optical disc is counted as the optical disc is rotated. Where the detectable number of encoder spokes is other than a predetermined value, an error condition with respect to the optically writable label surface of the optical disc is indicated.
