摘要： PURPOSE: To realize surely a quasi-vertical magnetized film with high efficiency and to obtain high-density recording and a high reproduced output by providing a quasi-vertical magnetized film satisfying specified conditions on a nonmagnetic substrate.
CONSTITUTION: A nonmagnetic substrate a
2 is traveled in the direction as shown by the arrow, and brought into contact with the outer circumferential surface of a drum body 3 which is heated at 300°C, for example, and the substrate (b) is heated to 300°C. The evaporated atoms of a ferromagnetic metal rising up through a clearance 7 from the lower part is vapor-deposited at a vertical incidence angle on the surface of the substrate a
2 while the substrate is passed through the lower end surface of the drum body 3. After a quasi-vertical magnetized film (a) of formula 1 is formed, the film is wound around a roller 5. Meanwhile, HC in equation I shows the coersive force in the direction vertical to the surface of the film and the coercive force in the direction parallel to the surface of the film which is the traveling direction when the recording is reproduced, and M
r shows the remanent magnetization in the direction vertical to the surface of the film and the remainent magnetization in the direction parallel to the surface of the film which is the traveling direction when the recording is reproduced.
