Abstract

UN OPERADOR DE DISCO OPTICO INCLUYE UNA PRIMERA UNIDAD DE DETECCION (7, 8) QUE DETECTA UNA PRIMERA SEÑAL DE TIEMPO Y UNA PRIMERA SEÑAL DE ERROR, INDICANDO LA PRIMERA SEÑAL DE TIEMPO UN CODIGO DE TIEMPO DE LOS PRESURCOS DE UN DISCO OPTICO (1) GRABABLE, SIENDO LA PRIMERA SEÑAL DE ERROR INDICATIVA DE UN ERROR DE LA PRIMERA SEÑAL DE TIEMPO. UNA SEGUNDA SEÑAL DE DETECCION (5, 6) DETECTA UNA SEGUNDA SEÑAL DE TIEMPO Y UNA SEGUNDA SEÑAL DE ERROR, INDICANDO LA SEGUNDA SEÑAL DE TIEMPO UN CODIGO DE TIEMPO DE DATOS GRABADOS DEL DISCO (1), SIENDO LA SEGUNDA SEÑAL DE ERROR INDICATIVA DE UN ERROR DE LA SEGUNDA SEÑAL DE TIEMPO. UNA UNIDAD (9) DE DETERMINACION DE TIEMPO DETERMINA LA PRIMERA SEÑAL DE TIEMPO COMO TIEMPO EN CURSO CUANDO NO EXISTE ERROR DE LA PRIMERA SEÑAL DE TIEMPO INDICADO POR LA PRIMERA SEÑAL DE ERROR, Y DETERMINA LA SEGUNDA SEÑAL DE TIEMPO COMO EL TIEMPO EN CURSO CUANDO UN ERROR DE LA PRIMERA SEÑAL DE TIEMPO ESTA INDICADO POR LA PRIMERA SEÑAL DE ERROR Y NO EXISTE ERROR INDICADO EN LA SEGUNDA SEÑAL DE TIEMPO POR LA SEGUNDA SEÑAL DE ERROR. UN COMPARADOR (10) DETECTA SI EL TIEMPO EN CURSO DETERMINADO CONCUERDA CON UN TIEMPO DIANA. UN CODIFICADOR (11) COMIENZA ESCRIBIENDO DATOS EN EL DISCO CUANDO SE DETECTA UNA COINCIDENCIA DEL TIEMPO EN CURSO DETERMINADO Y EL TIEMPO DIANA ES DETECTADO.
