Abstract

PARA DISPOSITIVOS DE GRABACION, POR EJEMPLO GRABACION VHS EXISTEN TIPOS DE CASSETTE QUE PUEDEN PARECER LO MISMO PERO TIENEN TIEMPO DE DURACION MUY DIFERENTES. LA IDENTIFICACION DEL TIPO DE CASSETTE CORRESPONDIENTE CONSUME TIEMPO Y PUEDE SER A VECES INCIERTA. ES EL OBJETIVO DE LA INVENCION SIN EMBARGO, ACORTAR EL TIEMPO NECESARIO PARA LA DETERMINACION DE FORMA FIABLE DEL TIPO DE CASSETTE, ESPECIALMENTE PARA AQUELLOS TIPOS DE CASSETTE UTILIZADOS EN GRABADORES DE VIDEO VHS. EL TIPO DE CASSETTE CORRESPONDIENTE SE IDENTIFICA MEDIANTE RELACIONADO DE LAS CARACTERISTICAS DE MEDICION DEL ESPESOR DE LA CINTA CON UNA CARACTERISTICA DE LONGITUD O CANTIDAD DE TIPO EN UN CIRCUITO (40) DE EVALUACION QUE GENERA UNA SEÑAL DE SALIDA REPRESENTANDO EL TIPO DE CASSETTE QUE ES TOMADO POR EL DISPOSITIVO (41) DE INDICACION DEL APARATO PARA MOSTRAR EL TIPO DE CASSETTE. SE UTILIZA ESPECIALMENTE PARA GRABADORES VHS.
