Abstract

EN EL CIRCUITO DE CONTROL DE ENFOQUE Y DE PISTAS DE UN DISPOSITIVO DE GRABACION O DE REPRODUCCION, SE UTILIZAN PEQUEÑAS BOBINAS, POR EJEMPLO, A MODO DE REGULADORES. HAY DOS BOBINAS NORMALMENTE INTERCONECTADAS EN EL CIRCUITO DE CONTROL DE PISTAS. PUESTO QUE LOS ALAMBRES DE LA BOBINA SOLO TIENEN UN GROSOR DE 0,08 A 0,1 MM, NO SON FACILES DE SOLDAR. PARA EVITAR ESTA DIFICIL TAREA DE SOLDAR TALES ALAMBRES TAN FINOS ENTRE SI, UNA PRIMERA SOLUCION ES COLOCAR UNA LAMINA CONDUCTORA CON PISTAS CONDUCTORAS Y PUNTOS DE SOLDADURA EN LA QUE SE SOLDAN LOS ALAMBRES DE LA BOBINA. EN UNA SEGUNDA SOLUCION, LAS BOBINAS (S) ESTAN HECHAS A MODO DE CIRCUITO IMPRESO EN UNA LAMINA CONDUCTORA QUE PUEDE ESTAR HECHA DE UN MATERIAL FLEXIBLE. ADEMAS, SE PUEDE COLOCAR VARIAS BOBINAS (S) LADO A LADO EN LA LAMINA CONDUCTORA, QUE SE PUEDE PLEGAR, DE MODO QUE HAY UNA BOBINA (S) EN CADA LAMINA PLEGADA. ESTO AUMENTA LA INTENSIDAD DEL CAMPO MAGNETICO.
