The recording medium has an optically transparent substrate, a thermally alterable recording layer consisting of an amorphous lanthanide transition metal alloy and, on that side of this recording layer which faces away from the substrate, an anticorrosion layer containing carbides, nitrides and/or oxides, wherein the anticorrosion layer… a) is 30 to 250 nm thick and… b) consists of two or more components which… c) are present in four or more separate layers, each comprising one of the components, wherein… d) at least one of the components is selected from the group consisting of the elements boron, aluminium, silicon, titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum and tungsten and… e) at least one other of the components is selected from the group consisting of the carbides, nitrides and oxides of these elements (d) and wherein… f) directly adjacent layers always consist of components which differ from one another. |
