发明名称 PRODUCTION OF MAGNETIC RECORDING MEDIUM
摘要 PURPOSE:To obtain a large quantity of magnetic recording media which have good durability and are suitable for high-density digital recording by allowing sputtering vapor deposition to be executed simultaneously in a high incident part at the time of forming a magnetic recording layer on a high-polymer film moving along a rotary support by a diagonal vapor deposition method. CONSTITUTION:The sputtering vapor deposition is simultaneously executed in the high incident angle part at the time of subjecting the high-polymer film 15 moving along the rotary support 16 to diagonal vapor deposition. The high incident angle part is, therefore, subjected to the diagonal vapor deposition and moreover, the film formation is initially executed at nearly the perpendicular incident in the sputtering vapor deposition having energy, by which the durability is improved and the uniformity is improved. In addition, the constituting material is formed with the sputtered layer of a material having the components approximate to the vapor deposition components. The recording is, therefore, not formed as a heterogeneous layer and the control of the magnetic characteristics equiv. to single vapor deposition is permitted. The good characteristics as the magnetic recording medium to be used for digital recording at the increased density are thereby maintained and the production of a large quantity of said media is permitted.
