Es un sistema obsoleto desde hace muchos a\u00f1os. Un tambor magn\u00e9tico est\u00e1 constituido por un cilindro recubierto de un material imanable. Las pistas aqu\u00ed son circunferencias de igual radio inmersas en la superficie del tambor. Al igual que en los discos, cada pista est\u00e1 compuesta de sectores.<\/p>\n

El tambor se encuentra girando a una velocidad uniforme y las cabezas lectoras\/grabadoras se sit\u00faan a lo largo de una generatriz del tambor esperando a que el sector a acceder se posicione delante de ellas.<\/p>\n

Hab\u00eda tambores con cabezas fijas y tambores con cabezas m\u00f3viles. Los de cabezas fijas tienen tantas cabezas como pistas, viniendo impuesto el tiempo de acceso por la velocidad de rotaci\u00f3n. En los de cabezas m\u00f3viles, una misma cabeza se encarga de acceder a varias pistas, teni\u00e9ndose que desplazar \u00e9stas a lo largo de una generatriz para acceder a la pista correspondiente. El tiempo de acceso vendr\u00e1 impuesto por el tiempo de b\u00fasqueda de la pista y el tiempo de espera del sector.<\/p>\n

Hace bastante tiempo que los tambores magn\u00e9ticos est\u00e1n en desuso, ya que son soportes no intercambiables y son ampliamente superados en prestaciones por los discos.<\/p>\n","protected":false},"excerpt":{"rendered":"
