The invention relates to an information carrier for scanning information by means of an optical beam having a wave-length. The information carrier comprises a central hole (11) and at least two information stacks (13, 14) rolled up around said hole. Each information stack comprises a first electrode, a second electrode and a material whose optical properties at the wavelength of the optical beam depend on a potential difference applied between the first and second electrodes.
