PURPOSE:To simplify manufacturing process of a diskette and stabilize the quality by providing projection inside a jacket. CONSTITUTION:The jacket 9 of a diskette is formed by integrally molding a flexible sheet which is made nearly flat on one face while projections 10 are provided on another face. A disk 1 is put therein, and the projections 10 are made to come into contact with the disk. When the projections 10 come into contact with the disk, the generation of static electricity is prevented by the electrical conductivity of carbon in the flexible sheet. |
