Abstract

APARATO REPRODUCTOR DE INFORMACION A PARTIR DE UNA PISTA DE REGISTRO MAGNETICO. COMPRENDE: UN CIRCUITO AMPLIFICADOR (9) QUE TIENE DOS TERMINALES DE ENTRADA (7, 8), CONECTADOS A LAS SALIDAS DE LAS DOS PORCIONES DE REPRODUCCION (2, 3) EN QUE SE DIVIDE LA CABEZA (1) DE REPRODUCCION, UNA PRIMERA UNIDAD (11) DE COMBINACION DE SEÑALES, AL MENOS UN AMPLIFICADOR CONTROLABLE (12, 14), Y UN TERMINAL DE SALIDA (16). EL CONTROL SE EFECTUA DE MODO QUE AL SER APLICADAS DOS SEÑALES DE LA MISMA FASE AL PRIMERO O SEGUNDO TERMINAL DE ENTRADA, SE OBTIENE UNA SEÑAL EN EL TERMINAL DE SALIDA (16) CON UNA AMPLITUD QUE SE ENCUENTRA EN RELACION FIJA CON LA DE LA MAYOR DE LAS DOS SEÑALES APLICADAS.
