Abstract

PURPOSE:To produce a magnetic recording medium which is uniform in film thickness and is excellent in durability by bringing the surfaces of a 1st web on which a magnetic coated film is formed and a 2nd web on which a thin film having surface lubricity is formed into tight contact with each other and taking up these webs in this state, then subjecting the webs to a heating treatment. CONSTITUTION:The web constituted by previously forming a required thin lubricating agent film on the surface of a suitable base material such as polyester film is prepd. The surfaces of this web and the web which is coated with a magnetic coating compd. and is subjected to a surface smoothing treatment to have the magnetic coated film in the uncured state are brought into tight contact with each other and the web are simultaneously taken up in this state; thereafter, the webs are subjected to the heating treatment so that the thin lubricating agent film is migrated on to the surface of the magnetic coated film. The thin lubricating agent film is previously coated on the base material and since this film is transferred onto the surface of the magnetic coated film, the suitable lubricating agent is formed to an adequate thickness and at a large degree of freedom for selection. As a result, the magnetic recording medium having the excellent durability is produced.
