Abstract

PURPOSE: To eliminate the need of a strong acid solution which has an adverse influence on a magnetic disc substrate such as Al, for instance, which corrodes the surface thereof, by coating onto a substrate a suspension in which crystalline fine particles of (aqueous) iron oxide are uniformly dispersed, and heat-treating the resultant film.
