Abstract: On the basis of the informative features describing each one of the co-mponents of a single magnetic disk, new informative features are presented, which form a substantial subset of the informative features of a single magnetic disk. This subset is limited to the composition of the substrate material and the functional layers a magnetic coating, anti-corrosion coating, protective coating and a lubricate layer.

Keywords: magnetic hard disk, information carriers, informative features.
