The surface at the structured zone (7,8) is formed by etching or a laser beam, to give a surface with a fine structure. A number of zones are formed on the disk surface as bar code markings. The light to register the marked zones on the disk surface is a laser beam (9). The disk (1) has a solid body (2) with a center drilling (4), and a polished aerodynamic surface, pref. with at least partial concave side surfaces. The marked surface zones (7,8) are at an angle, in the radial direction.
