| abstract | PURPOSE: To improve durability, output, oxidation resistance and anti electrification effect and to permit high-recording density by incorporating magnetic particle of which at least the surface is iron carbide and in which the content of the iron carbide is specific onto a recording layer on a flexible substrate. n CONSTITUTION: The magnetic particle of which at least the surface is the iron carbide and the content of the iron carbide in the particle is 5W90wt% is used as the magnetic particle of the recording layer into which the magnetic particle and binder are incorporated and which is provided on the flexible substrate. The compsn. of the iron carbide of the particle of which at least the surface is iron carbide is Fe n C (n>2) and magnetic metallic particle, γ-iron oxide parti cle, Co-deposited iron oxide particle or magnetic particle contg. Ba or Sr ferrite particle is preferable as the magnetic particle. The durability, wear resistance and the hardness of the coated film are upgraded by using such magnetic parti cle having the iron carbide on the surface. The chemical and magnetical stability against temp. and humidity environment is improved. Since the iron carbide is electrically conductive, the satd. magnetization is high and the magnetic disk having high recording density is obtd. n COPYRIGHT: (C)1987,JPO&Japio |
