Abstract

UN APARATO PARA GRABAR UNA SEÑAL ELECTRICA (A) EN UN SOPORTE DE GRABACION MAGNETICO (1) CONSTA DE AL MENOS UN PAR DE CABEZALES DE ESCRITURA (K1, K2) QUE TENGAN UN ACOPLAMIENTO MECANICO RIGIDO EL UNO AL OTRO Y DISPUESTOS EN UN TAMBOR DE CABEZAL (40) . EL SOPORTE DE GRABACION (1) SE ENVUELVE ALREDEDOR DEL TAMBOR DEL CABEZAL A TRAVES DE UN ANGULO DE CUBRIMIENTO (FIG. A) . EL PAR DE CABEZALES (K1, K2) ESCRIBE PARES DE PISTAS (T1, T2; T3, T4; ...) EN EL SOPORTE DE GRABACION. EL APARATO COMPRENDE ADEMAS DE UN SEPARADOR DE LA SEÑAL (4) PARA DIVIDIR LA SEÑAL ELECTRICA EN BLOQUES CONSECUTIVOS, DESPUES DE QUE LOS BLOQUES DE LA SEÑAL QUE TENGAN NUMERO DE SECUENCIA IMPAR (B1, B3, ...) SE APLICAN A UNA PRIMERA SALIDA (5) Y LOS BLOQUES DE SEÑAL QUE TENGAN NUMERO DE SECUENCIA PAR (B2, B4, ...) SE APLICAN A UNA SEGUNDA SEÑAL DE SALIDA (6) . EN UN CIRCUITO DE CORRECCION BASE DE TIEMPOS (7) SE EXPANDEN O COMPRIMEN EN EL TIEMPO LOS BLOQUES DE SEÑAL (A1, A2) . (FIG. B) ES DISTINTO A 180 . LOS BLOQUES DE SEÑALQUE TENGAN NUMERO DE SECUENCIA IMPAR SE RETRASAN EN EL TIEMPO RELATIVAMENTE A LOS BLOQUES DE SEÑAL QUE TENGAN NUMERO DE SECUENCIA PAR (16) . SUBSECUENTEMENTE, LOS BLOQUES DE SEÑAL PROCESADOS DE ESTE MODO SON GRABADOS. LA COMPRENSION O EXPANSION DE TIEMPO SE EFECTUA POR UN FACTOR DE (FIG. C) , DONDE N ES EL NUMERO DE PARES DE CABEZALES Y M ES EL NUMERO DE VECES DENTRO DE UN INTERVALO ESPECIFICO DE TIEMPO EN EL QUE UN PAR CABEZAL QUE CONTACTA CON EL SOPORTE DE GRABACION DURANTE DICHO INTERVALO DE TIEMPO Y NO GRABA SEÑAL ALGUNA EN EL SOPORTE, ESTANDO DICHO INTERVALO DE TIEMPO DEFINIDO POR AQUELLOS INSTANTES EN QUE AL MENOS DOS PARES DE PISTAS CONSECUTIVAS SE GRABAN POR UNO O DOS PARES DE CABEZALES. ADEMAS, SE DESCRIBE UN APARATO PARA REPRODUCIR LA SEÑAL GRABADA POR MEDIO DE DICHO APARATO DE GRABACION.
