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.A METHOD AND APPARATUS APPLICABLE TO A THERMAL RECORDING SYSTEM THAT RECORDS DATA IN A RECORDING MEDIA USING A GENERATED HEAT BY APPLYING A CURRENT TO A RESISTOR. ACCORDING TO THE INVENTION, THE SAME RESISTOR OR A MONITOR, WHICH IS PLACED ON THE PATH OF THE ELECTRIC CURRENT APPLIED TO THE RESISTANCE, IS MADE OF A MATERIAL THAT HAS METAL / NON-METALLIC PHASE TRANSITION CHARACTERISTICS AT A DEFAULT TEMPERATURE, WITH THAT THE RESISTOR OR MONITOR MAY HAVE A FUNCTION TO DISCONTINUE THE ELECTRICAL CURRENT AT THE DEFAULT TEMPERATURE SO THAT THE MAXIMUM TEMPERATURE OF THE RESISTANCE IS CONSTANTLY CONTROLLED REGARDLESS OF THE VALUE OR PERIOD OF THE APPLIED VOLTAGE. FURTHER, REACH A UNIFORM REGISTRATION PROPERTY AND A STABLE CONTINUOUS TONE REGISTRATION PROPERTY BY CONTROLLING THE PERIOD TO MAINTAIN MAXIMUM RESISTANCE TEMPERATURE.
