ABSTRACT:
A floppy disc structure comprises a magnetic disc which is rotatably disposed in a rectangular casing. At points where a gripping arrangement grasps the floppy disc in order to draw the same into a floppy disc drive unit automatically, spacers are provided which prevent compression of the casing, the spacers being disposed between the inner surfaces of the walls of the casing. The spacers are approximately the thickness of the magnetic disc.
