ABSTRACT:
A hub, on which compressing of the inner central bore is to be minimized during the winding up of an information medium in tape form under high winding pressure. According to one embodiment, this is achieved by an outer hub ring having a strong profile being provided alongside the outer windung area and by there also being elastically deformable intermediate elements between outer hub ring and inner hub ring. Such elements provide for a compression ratio of the compressed diameters of a the inner to the outer ring of less than 1:4. In the case of a further embodiment, variously shaped openings or notches, which are distributed evenly over the entire circumference, are provided on both sides of the hub between its outer circumference and inner circumference. In a still further embodiment the elastically deformable intermediate elements consist of webs running in radial and circumferential directions and residual portions between openings provided between the periphery of the outer ring and said webs.
