Radiation-sensitive material and method for recording information on radiation-sensitive material

摘要

A radiation-sensitive material comprising a metallic layer, an inorganic material layer, and a separation layer disposed between the metallic layer and the inorganic material layer and made from a material inert relative to these layers. The thickness of the separation layer is sufficient to interaction between the metallic layer and the inorganic material layer when said radiation material is exposed to actinic radiation having a power density lower than a threshold value required for causing a local breakdown of the separation layer. A method for recording information on a radiation-sensitive material of the above type, comprising irradiation of said material by pulses of electromagnetic or corpuscular radiation of a duration from 10-6 to 10-8 s with the energy density in the area exposed to radiation being not less than 5.10 J/cm2, said pulses being capable of producing between the metallic layer and the inorganic material layer in the exposed area of the radiation sensitive material a potential difference so as to cause an electric breakdown of the separation layer in said area.
