Abstract

PURPOSE:To improve the flexibility of magnetic layers and the durability by increasing the content of an org. high-polymer compd. in the middle at the time of forming the magnetic layers. CONSTITUTION:Cobalt 17 in a vapor source 16 in the lower part in a vacuum vessel 1 is evaporated by heating and polyethylene (PE) 19 in a vapor source 18 is simultaneously evaporated by heating so that the magnetic layer dispersed with the cobalt 17 at 85wt.% ratio in the PE 19 is formed by vacuum deposition. The cobalt 17 in a vapor source 20 and the PE 19 in a vapor source 21 are similarly deposited by vacuum evaporation to laminate and form the magnetic layer contg. 60wt.% cobalt 17 in the PE 19. The cobalt 17 in a vapor source 22 is similarly incorporated at 85wt.% into the PE 19 in a vapor source 23 to laminate the magnetic layer. As a result, the magnetic tape A integrally laminated with the magnetic layers 27, 28, 29 on a polyester film 6 is obtd.
