ABSTRACT:
To cement UV radiation-transmitting substrates to one another without deformation and within a short time, and to cement them together with high efficiency without an aluminum film of an information recording layer melting, according to the invention, a device for bonding discs to one another is provided having a radiant light source which irradiates the discs with radiant light which contains ultraviolet radiation at least once in a flash; a wavelength selector which is placed in the optical path between the radiant light source and the discs at a distance from the discs, which transmits the ultraviolet rays and absorbs light in a range of wavelengths which are absorbed by the UV radiation-transmitting substrates of the discs; a cooling device which admits and discharges cooling air between the radiant light source and the wavelength selector.
