Abstract

UN METODO Y APARATO APLICABLES A UN SISTEMA DE REGISTRO TERMICO QUE REGISTRA DATOS EN UN MEDIO DE REGISTRO USANDO UN CALOR GENERADO APLICANDO UNA CORRIENTE A UNA RESISTENCIA. DE ACUERDO CON EL INVENTO LA MISMA RESISTENCIA O UN MONITOR, QUE SE COLOCA EN LA TRAYECTORIA DE LA CORRIENTE ELECTRICA APLICADA A LA RESISTENCIA, SE HACE DE UN MATERIAL QUE TENGA CARACTERISTICAS DE TRANSICION DE FASE METALICA/NO METALICA A UNA TEMPERATURA PREDETERMINADA, CON LO QUE LA RESISTENCIA O EL MONITOR PUEDEN TENER UNA FUNCION PARA INTERRUMPIR LA CORRIENTE ELECTRICA A LA TEMPERATURA PREDETERMINADA DE FORMA QUE LA TEMPERATURA MAXIMA DE LA RESISTENCIA SE CONTROLE CONSTANTEMENTE INDEPENDIENTEMENTE DEL VALOR O PERIODO DEL VOLTAJE APLICADO. ADEMAS, ALCANZA UNA PROPIEDAD DE REGISTRO UNIFORME Y UNA PROPIEDAD DE REGISTRO DE TONO CONTINUO ESTABLE CONTROLANDO EL PERIODO PARA MANTENER LA TEMPERATURA MAXIMA DE LA RESISTENCIA.
