Abstract

METODO PARA SELECCIONAR LA INTENSIDAD MAXIMA OPTIMA DE UN HAZ DE LUZ USADO EN EL REGISTRO DE UNA SEÑAL DE INFORMACION, MODULADA EN FRECUENCIA, SOBRE UN MEDIO DISCOIDAL DE REGISTRO. COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE MODULA LA INTENSIDAD DEL HAZ DE LUZ DE ACUERDO CON UNA SEÑAL DE ENSAYO PREDETERMINADA, SIENDO LA INTENSIDAD ALTERNATIVAMENTE MAYOR Y MENOR QUE EL UMBRAL DE REGISTRO PREDETERMINADO DE LA CAPA DE FOTO-RESERVA; SEGUNDA, SE DIRIGE EL HAZ DE LUZ MODULADO EN INTENSIDAD SOBRE LA CAPA DE FOTO-RESERVA A MEDIDA QUE ESTA SE HACE GIRAR DE UN MODO PREDETERMINADO, PARA FORMAR UNA SECUENCIA DE PISTAS DE REGISTRO CIRCULARES Y CONCENTRICAS; Y POR ULTIMO, SE AJUSTA LA INTENSIDAD MAXIMA DEL HAZ LUMINOSO, MODULADO EN INTENSIDAD, PARA CADA UNO DE LOS GRUPOS DE PISTAS DE REGISTRO.
