Abstract

SE PRESENTA UN MATERIAL DE FTALOCIANINA ABSORBENTE DE LA BANDA CERCANA AL INFRARROJO QUE TIENE UN GRUPO DE SILIL COMO SUSTITUYENTE INTRODUCIDO EN EL ANILLO DE BENZENO DEL ESQUELETO DE LA FTALOCIANINA, Y UN MEDIO DE GRABACION OPTICA DE INFORMACION QUE CONTIENE ESTE MATERIAL. EL MATERIAL ES EXCELENTE EN SU CAPACIDAD PARA INHIBIR LA ASOCIACION Y DISIPACION DE LA LUZ, TIENE UN ALTO INDICE REFRACTIVO EN LA REGION DE LONGITUD DE ONDA DE ENTRE 770 Y 830 NM, Y ES ALTAMENTE SEGURO. COMO RESULTADO, UN MEDIO DE GRABACION OPTICA DE GRABACION (UN MEDIO DE GRABACION CDR) HECHO CON ESTE MATERIAL TIENE UNA ALTA REFLECTANCIA Y UNA ESTABILIDAD DE ALMACENAMIENTO Y REPRODUCCION EXCELENTE. ADEMAS ESTE MEDIO TIENE UNA ABSORCION Y UNA REFLECTIVIDAD DE LUZ EN LA REGION DE LONGITUD DE ONDA DE ENTRE 630 Y 720 NM Y ES APLICABLE A UN REPRODUCTOR DE DISCOS UTILIZANDO UN LASER SEMICONDUCTOR DE 630-720 NM. DE ESTA FORMA SE PUEDE CONSEGUIR UNA DENSIDAD DE GRABACION ENTRE 1.6 Y 1.7 VECES MAS ALTA QUE LA DE LOS MEDIOS DE GRABACION ACTUALES ADAPTADOS PARA SU USO EN UNA REGION DE LONGITUD DE ONDA DE ENTRE 770 Y 830 NM.
