ABSTRACT:
A method for producing a magnetic recording composition involves preparing an aqeuous dispersion of magnetic particles and colloidal silica particles, the pH of this dispersion being adjusted so that the magnetic and silica particles are electrostatically attracted to and bond to each other, removing the water from the dispersion, and dispersing the silica-coated magnetic particles in an organic liquid binder system for application to a recording substrate.
