摘要 |
A process of producing a magnetic recording medium comprises continuously circulating a magnetic coating composition prepared by dispersing a ferromagnetic powder in a solution of a high molecular binder while applying an ultrasonic treatment to the circulating magnetic coating composition, drawing out an amount of the ultrasonically treated magnetic coating composition necessary for coating from the circulating stream, and then coating the magnetic coating composition which is drawn out on to a non-magnetic support.
