Abstract: A data storage disc carrier (1) for carrying discs (10). The carrier includes an axial clamping mechanism which incorporates a three legged resilient clamping member (7) that can flees between release and clamping positions to allow easy loading a gripping of discs (10). The clamping member is articulatingly mounted on a tail (4) that is gripped to provide clamping.
