FIELD: data carriers manufacturing technologies.
SUBSTANCE: method includes drying and melting down of source polymer, pressing melt in fixed disk-shaped press-form, containing matrix with information, hardening of melt during cooling, extraction of disk from press-form, applying of reflective layer, covering of reflective layer by protective film by centrifuging in the air, ultraviolet drying of film, applying of sticker. Disk is cooled in press-form. Transporting of source polymer is performed at temperature 90°C-120°C and till value of allowed remaining moisture level for polymer in weight percents no more than 0.02 during applying of reflective layer and cooling of disk, temperature of coolant fed to press-form and applying device is preserved within range from +4°C to +24°C. applying of sticker is performed by paints hardened by ultraviolet.
EFFECT: higher reliability, higher effectiveness.
