<p>The invention provides a master disc comprising a stack of a substrate (10), a phase transition material layer (40), a heat absorption layer (30) provided between the substrate (10) and the phase transition layer (40), and an anisotropic heat sink layer (20) provided between the substrate (10) and the absorption layer (30). Further, a method of manufacturing a master disc is provided. A stack having an upper side and a lower side is provided, wherein the stack comprises a substrate (10) provided at the lower side of the stack, a phase transition material layer (40), a heat absorption layer (30) provided between the substrate (10) and the phase transition layer (40), and an anisotropic heat sink layer (20) provided between the substrate (10) and the absorption layer (30). The upper side of the stack is exposed to a laser beam (11) and developed.</p> |
