Abstract

SU APLICACION SE REFIERE AL METODO DE UN EQUIPO PARA FORMAR AREAS TENIENDO PROPIEDADES OPTICAS MODIFICADAS EN SU LECHO (3). EL LECHO (3) ES CALENTADO PARCIALMENTE A UNA TEMPERATURA FIJADA POR ENCIMA DE LA TEMPERATURA PREVISTA POR EL MEDIDOR DE DICHO LECHO MEDIANTE UN DESTELLO DE RADIACION (7, 107A) CUYA POTENCIA (P) ES AJUSTADA DE ACUERDO CON EL DISEÑO DE PULSACION (4A). UNA SEÑAL DE FORMACION RAPIDA (A(T)), LA CUAL ES INDICATIVA DE LA VELOCIDAD CON LA CUAL ESTAN FORMADAS LAS AREAS, ES DERIVADA DE LA RADIACION REFLEJADA EN EL LECHO (3) POR MEDIO DE UN CIRCUITO DE MEDIDAS (50), FORMADO POR UN CIRCUITO DE AJUSTE (12). EL CIRCUITO DE AJUSTE (12) ADEMAS COMPRENDE UN CIRCUITO (6), EL CUAL ADAPTA EL VALOR DE LA SEÑAL AJUSTADA (IH) PARA JUSTAR LA POTENCIA ESCRITA, DEPENDIENDO HASTA LA FORMACION DE LA SEÑAL DE VELOCIDAD (A(T)). ESTO REDUCE SUSTANCIALMENTE LA INFLUENCIA DE LOS CAMBIOS DE CONDICIONES DE MEMORIAS SOBRE LAS DIMENSIONES DE LAS AREAS DE GRABACION, TENIENDO MODIFICADAS LAS PROPIEDADES OPTICAS.
