Abstract

PURPOSE:To obtain a floppy disk with durability on the temperature conditions of a wide range by using a woven cloth containing a polyacrylonitrile fiber for liners, and containing an unsaturated fatty acid ester as a lubricant for a magnetic disk. CONSTITUTION:For liners 31 and 32 brought into contact with a magnetic disk 1, the woven cloth containing the polyacrylonitrile fiber is used. For a magnetic layer, the ester of an olefin acid, a linolic acid, etc., and a monovalent alcohol of about C 6-18 or a glycerol, a sorbitan, etc., is used as the lubricant, and it is contained by 2-20pts.wt. per 100pts.wt. magnetic powder. For a binder, a polyurethane is used, and in order to improve the durability of the magnetic layer, various kinds of hardeners such as an isocyanate may be used. By such a constitution, the floppy disk with high reliability and the high durability can be obtained.
