High storage density information carriers, particularly optically readable video discs and digital records, can only be read error-free by a playback device when the high requirements made of freedom from warping also remain guaranteed over long storage times. A cassette is provided to support and fix an information carrier only within its central portion which is free of information tracks and, by a sufficient spacing of the information carrier in the support-free area between a bottom portion and a cover portion contact with the information carrier in this area is avoided, even given consideration of maximally-admissible warping tolerances of the storage cassette and of the information carrier.
