Abstract

EN UN DISPOSITIVO DE SEGUIMIENTO DE PISTAS DINAMICO DE CABEZA MAGNETICA ROTATIVA DE LA PRESENTE INVENCION, HAY INSTALADOS A MODO DE ANILLO, ALREDEDOR DE UN EJE DE ROTACION, UNA BOBINA PARA GENERAR UN CAMPO MAGNETICO DE CONTROL QUE DESPLAZA A UNA CABEZA MAGNETICA A LO LARGO DE SU EJE DE ROTACION, UN IMAN PARA GENERAR UN CAMPO MAGNETICO CONSTANTE, UNA SECCION DE CULATA PARA PERMITIR QUE EL CAMPO MAGNETICO CONSTANTE FORME UN BUCLE CERRADO (POR EJEMPLO, UNA CULATA SUPERIOR Y UNA CULATA INFERIOR). EL TAMBOR INFERIOR FUNCIONA TAMBIEN COMO UN TAMBOR FIJO. UN MIEMBRO DE SOPORTE DE CABEZAS, QUE TIENE UNAS RANURAS ESPIRALES FORMADAS A LO LARGO DE SU SECCION DE BORDE EXTERIOR, SE ENCUENTRA FIJADO A LA CARA INFERIOR DE LA PARED CIRCUNFERENCIAL EXTERIOR DEL TAMBOR SUPERIOR. EL TAMBOR SUPERIOR Y UNA SECCION DE NUCLEO DE TRANSFORMADOR ROTATIVA SE ENCUENTRAN FIJADOS A UN CILINDRO ROTATIVO LO QUE HACE QUE ROTEN JUNTO CON UNA SECCION DE MOTOR Y EL MIEMBRO DE SOPORTE DE CABEZAS A MODO DE UNIDAD. ESTA DISPOSICION HACE QUE SEA POSIBLE LOGRAR QUE EL DISPOSITIVO DE SEGUIMIENTO DE PISTAS DINAMICO DE CABEZAS MAGNETICAS ROTATIVAS SEA COMPACTO Y QUE PROPORCIONES UNAS PRESTACIONES SUPERIORES TALES COMO: UNA MEJOR CARACTERISTICA DE RESPUESTA DEL MECANISMO DE AJUSTE DEL DESPLAZAMIENTO DE LAS CABEZAS; UNA REDUCCION DEL REOSTATO DE LA CINTA MAGNETICA; Y UN CONSUMO DE ENERGIA REDUCIDO.
