Abstract
There is suggested according to the invention that when gluing together information-carrying disc substrates into an optical, data-storing disc, there be used an adhesive in which there is mixed an evenly distributed trace amount of a fluorophore. This makes it possible, by measuring the fluorescent light, to determine and check the thickness of the adhesive layer between the substrates.
