Abstract
SE DESCRIBE UN REGISTRO (1) QUE TIENE UNA PISTA (4) QUE CONSTA DE UN AREA DE GRABACION DE INFORMACION (4B) EN LA QUE LA INFORMACION PUEDE SER GRABADA COMO UN PATRON DE MARCAS DE GRABACION (40) CON PROPIEDADES OPTICAS MODIFICADAS. EN UNA POSICION PREDETERMINADA (4A) DE LA PISTA (4) SE GRABA LA INFORMACION DE CONTROL COMO UNA ESTRUCTURA DE INFORMACION PREFORMADA (FIG. 1C, FIG. 1D), CUYA INFORMACION DE CONTROL ES INDICATIVA DE LA DIFERENCIA ENTRE LAS PROPIEDADES OPTICAS DE LAS MARCAS DE GRABACION (40) Y LAS AREAS INTERMEDIAS SITUADAS ENTRE DICHAS MARCAS DE GRABACION. LA INFORMACION GRABADA PUEDE SER LEIDA MEDIANTE UN APARATO DE LECTURA (10) QUE CONSTA DE ELEMENTOS DE EXPLORACION (13) PARA EXPLORAR LA PISTA (4) MEDIANTE UN HAZ DE RADIACION (11), ELEMENTOS TRANSDUCTORES OPTO-ELECTRONICOS (24) PARA CONVERTIR EL HAZ DE RADIACION REFLEJADO (11), Y UN DISPOSITIVO DE PROCESAMIENTO DE SEÑAL (15) PARA DERIVAR UNA SEÑAL DE INFORMACION (VO) QUE ES REPRESENTATIVA DE LA INFORMACION QUE SE HA LEIDO. ANTES DE LEER LA INFORMACION REGISTRADA EN EL AREA DE GRABACION DE INFORMACION (4B), LA INFORMACION DE CONTROL ES LEIDA EN UN AREA PREDETERMINADA (4A) DE LA PISTA (4) Y EL CIRCUITO DE PROCESAMIENTO DE SEÑAL (15) ES AJUSTADO MEDIANTE UN ELEMENTO DE AJUSTE (32,35) DE ACUERDO CON LA INFORMACION DE CONTROL LEIDA.
