摘要： In a process involving the successive formation of a soft magnetic film substantially consisting of Fe and Ni and a perpendicular magnetic film on a plastic substrate, the soft magnetic film is vacuum-deposited while its formation position is irradiated with an ion-beam so as to prevent cracks and lessen coercive force. Apparatus for carrying out the deposition of the soft magnetic film includes a vacuum chamber (8) divided by a partition (7) into an upper chamber (9) and a lower chamber (10) which can be exhausted through outlets (11) and (12). The film substrate strip (6) is fed from a roll (1) round a cooled drum (3) to a winder (5). An evaporator (16) contains an iron-nickel ingot (15), and ion-beam radiation issues from the source (17). A screen (13) has an aperture (14) which limits the incident angle of the ion-beam onto the position of the substrate (6) passing round the drum (3).

摘要： A vertical magnetic recording medium comprises substrate (4) and a magnetic layer (3) formed on the substrate (4) and having a magnetic anisotropy in the direction vertical to the surface of the substrate. The magnetic layer (3) is composed substantially of a metal selected from cobalt and/ or iron, and an oxide of the metal. The metal and metal oxide consist of columnar structures (1) oriented in the direction vertical to the surface of the substrate (4) and spaced from one another through fine voids (2) throughout the magnetic layer. The columnar structures (1) have a diameter of 100 to 1000 A and the magnetic layer (3) has a void ratio of 7 to 56%. The vertical magnetic recording medium is prepared by a process for vacuum-depositing a metal selected from cobalt and iron to form a magnetic layer on a substrate, wherein an oxygen gas and at least one gas chemically inactive in the vacuum deposition system, which is selected from nitrogen, argon, helium, neon, xenon, radon, methane and ethane, are introduced into the vacuum to an extent such that the pressure in the vicinity of the substrate is 1 x 10 3 to 5 x 10 2 Torr.
