ABSTRACT:
Disclosed is a magnetic disc cartridge of the type in which a magnetic disc assembly is supported for rotation within cartridge covers. Various improvements in the disc cartridge facilitate the manufacture and use thereof. For example, the cartridge inside cover is permanently secured to the cartridge top cover by a series of integral hooks on the inside cover and mating hook anchors on the top cover; a simplified release lever serves to draw the magnetic disc assembly away from the bottom cover when removal of the bottom cover from the remainder of the cartridge is desired; an improved snubber assembly is provided for inhibiting rotation of the disc assembly when the release lever is actuated; and an improved design of the hub which forms a part of the magnetic disc assembly permits the distortion-free operation of the hub, even when made from a synthetic plastic material.
