ABSTRACT:
A method is disclosed for positioning an optical labeling mechanism substantially close to a particular track of a labeling surface on an optical disk. The method can include the operation of positioning the optical labeling mechanism adjacent to the particular track. A further operation can be measuring a first surface texture of the labeling surface using the optical labeling mechanism. Another operation can involve positioning the optical labeling mechanism adjacent to a different track. A further operation can be moving the optical labeling mechanism from the different track toward the particular track location. Another operation can involve measuring a second surface texture of the labeling surface using the optical labeling mechanism. A further operation can be comparing the first and second surface textures to determine if the optical labeling mechanism is positioned substantially near the particular track.
