In laser recording systems, data is written in a thermoplastic medium and a smooth surface of the medium is critical for high quality operation of the system. This smooth recording surface is provided by spin coating the supporting substrate, which may be an unpolished metal, with an intermediate layer of thermosetting material which is nonconformal in nature. The thermoplastic medium which is conformal in nature is then spin coated onto the smooth surface provided by the intermediate layer to form a microscopically smooth conformal layer. |
