Abstract: PURPOSE:To prevent the generation of a camber by making a mechanical direction of each support of both flexible discs with at least the mechanical direction in the optical axis direction. CONSTITUTION:The flexible disc 2 on the support 4 of which a magnetic layer 5 is provided is sticked to both faces of a base 1. The gap 3 is provided for two purposes: to disperse the friction when a head and the magnetic layer 5 are contacted thereby strengthening the durability and to alloy the magnetic layer 5 to be in proper contact with the head causing very narrow spacing and high density recording. Thus, the depth (d) of the gap 3 requires at least <=0.1mm taking various conditions in operation into account. The MD direction of the support of each flexible disc at both sides of the base is arranged, prefer ably the MD direction and the optical axis direction are to be arranged.
