Abstract

METODO PARA FABRICAR UN DISCO DE INFORMACION OPTICA, EN EL QUE PUEDE ESCRIBIRSE Y LEERSE OPTICAMENTE INFORMACION. CONSISTE EN CUBRIR UNA PLACA DE SUSTRATO (1), EN AL MENOS UNA CARA, CON UNA CAPA DE REGISTRO (6) ABLATIVA FORMADA POR TELURO, SELENIO Y ANTIMONIO, SATISFACIENDO LA COMPOSICION DE DICHA CAPA DE REGISTRO LA FORMULA TE<XSE<YSB<ZSQ, EN LA QUE X SIGNIFICA UN NUMERO DE ATOMOS COMPRENDIDO ENTRE UN 55 Y UN 85%, Y SIGNIFICA UN NUMERO DE ATOMOS COMPRENDIDO ENTRE UN 13 Y UN 30%, Z SIGNIFICA UN NUMERO DE ATOMOS COMPRENDIDO ENTRE UN 1 Y UN 12%, Y Q SIGNIFICA UN NUMERO DE ATOMOS COMPRENDIDO ENTRE 0 Y UN 10%, SIENDO X+Y+Z+Q=100. LA PLACA DE SUSTRATO (1) SE LA PROVEE PRIMERAMENTE DE UNA CAPA DE LACA RETICULADA POR LA LUZ (2).
