Abstract
LA INVENCION SE REFIERE A UN SISTEMA DE GRABACION DE DATOS SOBRE DISCO OPTICO. LOS DISCOS OPTICOS ACTUALES, LEGIBLES CON LASERES DE LONGITUD DE ONDA VISIBLE (ENTRE 0,5 Y 0,8 MICRONES) TIENEN UNA DENSIDAD DE ALMACENAMIENTO EN SUPERFICIE QUE ES COMO MAXIMO DEL ORDEN DE UN BIT DE DATO POR ZONA ELEMENTAL DE SUPERFICIE DE APROXIMADAMENTE 1 MICRON CUADRADO. POR DEBAJO, LA DIFRACCION NO PERMITE DISTINGUIR ZONAS VECINAS. LA INVENCION PROPONE UN MEDIO PARA AUMENTAR CONSIDERABLEMENTE LAS CAPACIDADES DE ALMACENAMIENTO SE INSCRIBE EN UNA ZONA ELEMENTAL (14) DE UNA CAPA (16) UN BIT DE INFORMACION, NO EN FORMA DE UN PUNTO DE ABSORCION DE UNA LUZ LASER, SINO EN FORMA DE UNA RED DIFRACTANTE QUE TIENE UN PASO DETERMINADO. VARIAS REDES DIFRACTANTES DE PASO DIFERENTES UNAS DE OTRAS PUEDEN SUPERPONERSE EN EL MISMO PUNTO, PERMITIENDO LA INSCRIPCION EN UNA MISMA ZONA DEL DISCO DE VARIOS BITS DE INFORMACION. LAS REDES DEFRACTANTES SE REALIZAN POR UN HAZ DE LASER DE GRAN ENERGIA, EN UN MATERIAL CUYO INDICE PUEDE VARIAR EN FUNCION DE ESTA ENERGIA. LA LECTURA SE HACE POR UN LASER SINTONIZABLE EN FRECUENCIA QUE PERMITE DETECTAR, PARA DIFERENTES FRECUENCIAS, LA PRESENCIA O LA AUSENCIA DE REDES DIFRACTANTES.
