Abstract
Un método de hacer copias de soportes de información que tienen una banda de información similar a una espiral, o una banda formada de círculos concéntricos, en la que hay almacenada información en audio y/o video en forma de señales moduladas en frecuencia o en fase en forma de bloques de longitudes variables que están situados en el mismo plano liso, caracterizado por usar un material fotosensible conocido que consta de una capa de base en la que hay presente un compuesto fotosensible de un tipo que, después de la exposición, proporciona un producto de reacción con la luz que es capaz de reaccionar con iones mercuriosos en presencia de humedad, y preferiblemente además en presencia de iones de plata, al mismo tiempo que se separa mercurio o amalgama de plata que se deposita en forma de una imagen de núcleos metálicos físicamente revelables, compuesto fotosensible que es un diazosulfuro aromático de estructura.
