Abstract

PURPOSE:To prevent a disk from receiving the influence of a magnetic field from a ferromagnetic left in the vicinity thereof and to protect information recorded on the disk by coating the disk rotatably mounted in a shell with magnetic shield member. CONSTITUTION:The disk 2 of a flexible disk cassette is rotatably held and mounted between the upper shell 3 of a main body and a lower shell 4 and the disk 2 is protected by the respective shells 3, 4. A center plate 5 and a liner 6 etc. are concentrically disposed between the disk 2 and the shell 3 and a liner 9 is concentrically disposed on the lower face of the disk 2 to hold the disk 2 by the liners 6, 9. The magnetic shield plate 10 is mounted so as to cover the disk 2 internally of a pair of the shells 3, 4. A magnetic flux 15 generated by the strong magnetic field 1 from the ferromagnetic body left in the vicinity of the cassette is interrupted by the shield plate 10 to prevent the magnetic flux 15 from passing through the disk 2 and protect the information recorded on the disk 2.
