    Abstract: In a process for continuous refining of oils and fats, starting oils and fats and a lower alcohol containing 0.06 to 0.15 wt. %, based on the starting oils and fats, of an acid catalyst are continuously fed into a multi-stage reaction tank equipped with a stirrer and prevented from the back mixing, then the oils and fats are refined at 67 DEG C. or below, the refined oils and fats are continuously taken out together with an excess of the lower alcohol containing the acid catalyst, they are separated into the oil and fat layer and the lower alcohol layer, and most of the lower alcohol layer is recycled into the reaction tank.

    Abstract: PURPOSE:To uniformly and easily form fine ruggedness while maintaining high smoothness and to obtain a magnetic recording medium having high durability as well excellent recording and reproducing characteristics. CONSTITUTION:A magnetic thin film 2 of an alloy is formed on a nonmagnetic substrate to obtain the magnetic recording medium. Fine ruggedness due to the surface 3 of an aggregate of coarse crystal grains of the constituent components of the thin film is formed on the surface of the thin film.
