Summary:The recordable optical storage medium comprises a substrate layer (2), a data layer and a first and a second protection layer (6, 7) for the data layer, wherein the data layer comprises a semiconductor layer (3, 4) and a dopant layer (5) with a doping material usable for doping the semiconductor layer (3, 4). The semiconductor layer is in particular an intrinsic or essentially intrinsic semiconductor layer having a low reflectivity and the doping material of the dopant layer is selected such, that the reflectivity of the semiconductor layer is increased, when doping material of the dopant layer is diffused into the semiconductor layer.
