Abstract

The invention relates to an information carrier for scanning information by means of an optical beam (OB) having a wavelength, said information carrier comprising at least two information stacks. Each stack is a waveguide comprising two cladding layers (11, 14) and a waveguide core (13) between said two cladding layers. The waveguide comprises an information layer (12) comprising a photochromic material which optical properties at the wavelength of the optical beam can be switched by means of a light beam (LB) propagated into said waveguide.
