Abstract

EN UN APARATO DE GRABACION Y/O REPRODUCCION DE SEÑAL, QUE INCLUYE CUATRO CABEZAS MAGNETICAS (HD1,HD2,HD3,HD4) MONTADAS EN UN TAMBOR GIRATORIO (2) PARA FORMAR CUATRO PISTAS DE GRABACION PARALELAS (TA1,TA2,TA3,TA4) EN SECUENCIA REPETIDA SOBRE UN MEDIO DE GRABACION (1), TENIENDO CADA PISTA UN ANGULO DE INTERVALO AZIMUTAL DISTINTO DEL DE LA PISTA ADYACENTE, SE GRABAN DE FORMA SUPERPUESTA SEÑALES PILOTO (PL1,PL2,PL3,PL4) DE DIFERENTES FRECUENCIAS (F1,F2,F3,F4) SOBRE LAS SEÑALES DE INFORMACION (VIDEO) GRABADAS POR LAS CUATRO CABEZAS MAGNETICAS RESPECTIVAMENTE. EN LA REPRODUCCION, SE EFECTUA UN CONTROL DE PISTAS PARA GARANTIZAR QUE LAS CABEZAS MAGNETICAS (HD1,HD2,HD3,HD4) QUE GRABARON LAS SEÑALES PILOTO (PL1,PL2,PL3,PL4) CON DIFERENTES FRECUENCIAS SON LAS QUE REPRODUCEN LAS SEÑALES GRABADAS EN LAS PISTAS RESPECTIVAS, DE MANERA QUE UN PERIODO DE SEÑAL DE SINCRONIZACION, UNA SEÑAL SINCRONIZADORA HORIZONTAL POR EJEMPLO, CONTENIDA EN LA SEÑAL REPRODUCIDA (VIDEO) NO SE VEA AFECTADA AL CAMBIAR DE UNA AOTRA DE LAS CABEZAS (HD1,HD2,HD3,HD4) EN EL MODO DE REPRODUCCION.
