Abstract

UN DISPOSITIVO CAPTADOR Y/O CORTADOR PARA EXPLORAR Y/O CORTAR INFORMACION EN UNA PISTA DE UN PORTADOR DE REGISTRO DISCOIDAL. CONSTA DE UN PORTA-ESTILETE QUE LLEVA UN ESTILETE O AGUJA EN UN EXTREMO Y UNIDO EN EL OTRO EXTREMO A UN ELEMENTO MOVIBLE CAPAZ DE PIVOTAR EN TODAS DIRECCIONES Y DOS CIRCUITOS MAGNETICOS CADA UNO DE LOS CUALES LLEVA UNA PIEZA POLAR QUE COOPERAN CON EL ELEMENTO PIVOTANTE. EL CIRCUITO MAGNETICO CONTIENE UNA O MAS CAVIDADES QUE SE EXTIENDEN EN LA DIRECCION DE LAS LINEAS DE FUERZA MAGNETICAS; EL CIRCUITO MAGNETICO, TIENE AL MENOS UNA RANURA QUE SE EXTIENDE, EN LA DIRECCION DE LAS LINEAS DE FUERZA HACIA DENTRO DE LA CAVIDAD. LA PIEZA POLAR ESTA HECHA DE UN MATERIAL DE CHAPA OBTENIENDOSE POR DEFORMACION MECANICA.
