ABSTRACT The flexible disk of a flexible disk file is provided with a stationary backing plate over which the disk rotates supported on an air bearing between it and the plate. The plate has a longitudinal slot extending in a radial direction with respect to the disk to permit access by a record/playback head to the disk surface facing the plate. The backing plate is shaped in such a way that the rotating disk is continuously bent upwards about two chords on each side of a line through the head slot. The provision of these bends imparts stiffness to the disk in the vicinity of the head slot and stabilizes the flying characteristics of the disk. - 1 -
