ABSTRACT:
A method of manufacturing an optically readable information carrier in which a substrate 1 which is provided on at least one surface with a material which is sensitive to deep ultraviolet light having a wavelength from 190-300 nm, is exposed to deep ultraviolet light via a contact mask 2 which on one side has a layer 4 of a material which is not permeable to deep ultraviolet light in which an information track 5, 6 has been provided, after which the exposed plate is developed and if desired is provided with a reflection layer.
