A method of recording information in a laminated structure (003) including an intermediate layer (007) located between a transparent layer (006) and a non- absorbing layer (008). The method includes the steps of subjecting the laminated structure (003) to a pulsed beam of laser radiation so that the beam passes through the transparent layer (006) to be absorbed by the intermediate layer (007) to ablate areas of the intermediate layer (007), thus recording information in the laminated structure.
L'invention concerne un procédé qui permet d'enregistrer des informations sur une structure laminée (003) constituée d'une couche intermédiaire (007) disposée entre une couche transparente (006) et une couche non absorbante (008). Selon le procédé, on soumet la structure laminée (003) à un faisceau pulsé d'un rayonnement laser, de façon que ledit faisceau traverse la couche transparente (006) et soit absorbé par la couche intermédiaire (007), ce qui enlève certaines zones de cette dernière et permet ainsi d'enregistrer des informations dans la structure laminée.
