Abstract

EN REPRODUCTORES DE VIDEO CONOCIDOS, LA PALANCA SENSORA DE TENSION DE LA CINTA SE LEVANTA DE LA CINTA MAGNETICA AL CONMUTAR AL MODO DE FUNCIONAMIENTO DE BUSQUEDA MARCHA ATRAS Y LA TENSION DE LA CINTA EN ESTE MODO DE FUNCIONAMIENTO ESTA PREDETERMINADA POR UN ACOPLAMIENTO DE RESBALAMIENTO AJUSTADO FIJO. EL COMETIDO DE LA INVENCION, EN CASO DE CONMUTACION DEL MODO DE REPRODUCCION AL MODO DE BUSQUEDA MARCHA ATRAS, ES MANTENER LA TENSION DE LA CINTA AJUSTADA POR ULTIMO ASI COMO LA POSICION DE LA CINTA RELATIVAMENTE A LAS CABEZAS MAGNETICAS EN CONTACTO Y, POR OTRO LADO, CONTROLAR LA TENSION DE LA CINTA EN EL MODO DE BUSQUEDA MARCHA ATRAS A TRAVES DE LA PALANCA SENSORA DE TENSION DE LA CINTA. MEDIANTE UNA PALANCA DE BLOQUEO CONTROLABLE (13), SE DETIENE LA PALANCA SENSORA DE TENSION DE LA CINTA (11) EN LA ULTIMA POSICION TOMADA AL CAMBIAR AL MODO DE BUSQUEDA MARCHA ATRAS, DE MODO QUE POR EL AUMENTO DE LA TENSION DE LA CINTA EN EL MODO MARCHA ATRAS SE ELIMINA EL BLOQUEO. EL SIGUIENTE CONTROL DE LA TENSION DE LA CINTA TIENE LUGAR MEDIANTE UN ACOPLAMIENTO DE RESBALAMIENTO (14) AJUSTABLE EN SU EFECTO, QUE ES CONTROLADO MEDIANTE UN TRANSDUCTOR ELECTROMAGNETICO EN FUNCION DE LA POSICION DE LA PALANCA SENSORA DE TENSION DE LA CINTA.
