摘要: The optical storage medium comprises a substrate layer (52), read-only data (52a) with pit structure disposed on the layer, and nonlinear (54, 56) super-resolution above (52a), which includes semiconductor material grainy impurities of dielectric (55), wherein has an increased reflectivity, when irradiated laser beam, (55) is arranged as having thickness below 5 nm. consists advantageously inhomogeneous nitride material, for example GeN, between first second 56).
