Abstract
EN LOS PROCESOS DE COPIADO CONVENCIONALES, LAS SEÑALES GRABADAS ADEMAS DE LA INFORMACION UTIL ACTUAL, EJ. SEÑALES DE CONTROL PARA LA SINCRONIZACION DE LOS IMPULSOS DE CONMUTACION DE LA CABEZA GRABADORA, NO SON COPIADAS. LA INFORMACION ADICIONAL PUEDE SER SIN EMBARGO CODIFICADA EN UNA VARIACION DE ESTAS SEÑALES Y ASI ESTA INFORMACION TAMPOCO ES COPIADA . EN LA INVENCION, LA INFORMACION DIGITAL GRABADA EN LA PISTA DE CONTROL Y DETECTADA POR UN DISPOSITIVO DE REPRODUCCION ES TRANSMITIDA POR UNA ETAPA DE TRANSMISION A UN DISPOSITIVO DE GRABACION DONDE SE VUELVE A GRABAR DE MANERA DIGITALMENTE CODIFICADA EN UNA COMPUERTA DE TIEMPO APROPIADA EN LA PISTA DE CONTROL. EL PROCESO Y EL DISPOSITIVO SON UTILES PARA COPIAR CINTAS MAGNETICAS QUE CONTENGAN DIRECCIONES O MARCAS DE INDICES.
