ABSTRACT:
A method of manufacturing a magnetic recording medium that exhibits high performance and high reliability includes forming a liquid lubricant layer capable of high coverage while retaining a film thickness of 1 nm to 2 nm. The magnetic recording medium includes an underlayer, a magnetic layer, a protective layer, and a liquid lubricant layer sequentially laminated or formed on a substrate. The liquid lubricant layer is formed by coating a liquid lubricant diluted with a solvent on the protective layer to a thickness of at least the surface roughness to form a thick film liquid lubricant layer, pressing a slide member against the surface of the liquid lubricant layer while rotating the medium to adhere the liquid lubricant onto the protective layer, and reducing the thickness of the liquid lubricant layer with a solvent that can dissolve the liquid lubricant to the medium surface.
