Firstly, the material for disk is dried in the temperature of 125 Celsius. This way we receive a transparent disk which is cooled down and (in metallization) receives an aluminium layer. The whole process takes places in a vanity area with the use of argon. Metallized surface is evenly covered by special protective lacquer in the machine of high rotation speed. Ultraviolet lamp makes the lacquer hard. In the last stage, special optical device controls the quality of a disk determining its usefulness and eliminating worthless remains. All disk manufacturing process lasts from 3 to 4 seconds. Moreover, better and better quality control technology allows for lossless production process.
