Abstract

UN MEDIO DE REGISTRO CON RECUBRIMIENTO MAGNETICO ORIENTADO LONGITUDINALMENTE QUE COMPRENDE, AL MENOS, PARTICULAS MAGNETICAS PLANAS, CADA UNA DE LAS CUALES TIENE UN EJE DE MAGNETIZACION FACIL PERPENDICULAR A SU SUPERFICIE MAYOR, MEZCLADAS PREFERIBLEMENTE CON OTRAS PARTICULAS, Y DISPERSADAS EN UNA PELICULA MAGNETICA FORMADA SOBRE UN SUSTRATO NO MAGNETICO, CON UN ANGULO DE ORIENTACION DE -30G A +30G. UN PROCEDIMIENTO PARA PRODUCIR UN MEDIO DE REGISTRO DE ESTA CLASE COMPRENDE LA OPERACION DE ORIENTAR LAS PARTICULAS MAGNETICAS PLANAS MEDIANTE LA APLICACION DE, POR LO MENOS, UN CAMPO MAGNETICO APROXIMADAMENTE PARALELO A LA SUPERFICIE DE LA PELICULA MAGNETICA.
