Abstract

PURPOSE:To obtain a thin ferromagnetic film which has superior magnetic characteristics and sticking strength, by carrying out slanting vapor deposition and nearly vertical vapor deposition in succession during the manufacture of a magnetic recording medium obtained by vapor-depositing ferromagnetic metal or alloy particles on a tapelike base plate. CONSTITUTION:During the manufacture of a magnetic recording medium wherein a ferromagnetic film is formed by vapor-depositing ferromagnetic metal or alloy particles on a tapelike base plate 1 of polyethylene phthalate, etc., under vacuum, the vapor 6 of the ferromagnetic metal or alloy is caused to strike the surface of the base plate 1 slantingly at >=45 from the perpendicular of the base plate, thereby forming the 1st magnetic layer 2. On it, the 2nd magnetic layer 3 is formed by causing the vapor 6 to strike the surface of the base plate 1 at <30 and nearly at right angle, thus required magnetic recording medium. Consequently, particles having a small angle of incident enter the space of the 1st layer 2, so that the film having strong structure is formed.
