Abstract

Método para fabricar un portador de registro para almacenar información con densidad muy grande, donde un elemento fotosensible que comprende un portador de registro en forma de disco, que consiste al menos por un lado en material inorgánico hidrófilo que está provisto de una fotolaca, se expone intermitentemente durante tiempos variables, por el lado de la fotolaca, de acuerdo con la información a tratar, tras lo cual se revela la fotolaca y se forma una pista de información, caracterizado porque la fotolaca está dispuesta sobre una capa adherente de resina epoxídica endurecida, que a su vez está dispuesta sobre el material inorgánico hidrófilo.
