Abstract

METODO Y APARATO PARA CONTROLAR LA ALTURA DE FLOTACION DE UNA CABEZA MAGNETICA SOBRE UN MEDIO DE REGISTRO MOVIL, EN DONDE EL METODO IMPLICA BAJAR DICHA CABEZA HASTA LA DISTANCIA AERODINAMICA DE LA SUPERFICIE (16) DE DICHO MEDIO DE REGISTRO, BAJAR MAS DICHA CABEZA HASTA PRODUCIR UNA CORRIENTE TUNEL ENTRE ELLA Y DICHA SUPERFICIE, Y MANTENER CONSTANTE DICHA CORRIENTE UTILIZANDO SUS DESVIACIONES RESPECTO DE UN VALOR PREDETERMINADO. EL APARATO COMPRENDE UN ELECTRODO YUNEL (9) FIJADO A UN MECANISMO (5) DE CONTROL DE DISTANCIA Y DOTADO DE UN ASIENTO (45, 47) BISELADO PARA DETECTAR ANTICIPADAMENTE ASPEREZAS QUE SE APROXIMAN A LA CABEZA AL ASENTARSE SOBRE LA SUPERFICIE (16) DEL MEDIO DE REGISTRO (3). EL INVENTO ES APLICABLE A LAS UNIDADES DE MEMORIA MAGNETICA DE ALMACENAMIENTO DE DATOS.
