ABSTRACT:
The invention relates to a system optically recording information, by the insolation of a photosensitive layer deposited on a substrate, on a track of substantially constant width. The system comprises a device for controlling the energy emitted by the source in response to the non-uniformity of the reflexion coefficient of said surface, said control device being such that the energy actually transmitted to the photosensitive layer is constant when the modulation signal has the value 1.
