Abstract

PROCESO PARA LA FABRICACION DE MATRICES DE PRENSADO, PARTICULARMENTE PARA LA REALIZACION DE DISCOS DE LECTURA OPTICA, QUE CONSISTE, MEDIANTE UN APARATO ESTANDAR DEL MERCADO, EN GRABAR EN FORMA DE MICROSURCOS (14), UNA SEÑAL QUE CORRESPONDE A INFORMACIONES CODIFICADAS EN UNA CAPA DE RESINA TERMOSENSIBLE (11) DEPOSITADA SOBRE UN SUSTRATO RIGIDO (10) Y APTO PARA SER GRABADA BAJO EL EFECTO DE UNA RADIACION (1) A PARTIR DE UN DIODO LASER , ESTANDO DICHA CAPA PREVIAMENTE RECUBIERTA POR UN REVESTIMIENTO METALICO DELGADO REFLECTOR (12). ESTE PROCESO CONSISTE EN ELIMINAR EL REVESTIMIENTO REFLECTOR Y LA CAPA PROTECTORA PARA DESCUBRIR LOS MICROSURCOS PARA CONSTITUIR UN DISCO MAESTRO, EN DEPOSITAR SOBRE LA CAPA DE RESINA UN REVESTIMIENTO METALICO DELGADO PARA ADAPTARSE AL PERFIL DE LAS MICROSURCOS, Y DESPUES EN DEPOSITAR UNA CAPA METALICA FINAL SOBRE EL REVESTIMIENTO PARA FORMAR UNA MATRIZ DE IMPRESION QUE COMPRENDE MICRORRELIEVES QUE CORRESPONDEN A LOS MICROSURCOS Y POR FIN EN PRENSAR POSTERIORMENTE SOBRE DICHA MATRIZ LOS DISCOS OPTICOS O ANALOGOS A FABRICAR.
