Date Jan. 18, 1996A winding hub for tape information carriers is designed with spring elements between an inner ring and an outer ring for providing a compression ratio from the inner diameter to the outer diameter of less than 1:4. To increase the holding forces of the winding hub during reeling, the spring elements are assigned limiter elements.

Abstract: A magnetic recording material contains a layer comprising a magnetic pigment and a polyurethane binder (I) prepared by reacting an isocyanate (II) with a chain extender (V).(II) are (a) prepolymers prepared by reacting (A1) a polyvalent alcohol (III) containing more than one hydroxyl group per molecule capable of reacting with (II), with (A2) an aromatic or aliphatic polyvalent isocyanate (IV), or (b) compounds (IV). The ratio of reactive hydroxyl groups in (III) to the isocyanate groups in (IV) is less than 1. (V) are prepared by reacting (a) a polyvalent alcohol (VI) with either (b1) a compound (VII) containing an epoxy group and an additional functional group which is reactive with alcohols, forming a compound (VIII) which is reacted with an alpha,beta-olefinic unsaturated carboxylic acid (IX) to form a compound (X), or (b2) a compound (IX) to form a compound (X), and then (c) reacting (X) with an amine (XI) containing at least one prim. amino group which can react with olefinic bond in (IX). The sum of reactive amino and hydroxyl groups in (V) is greater than the number of isocyanate groups in (II).

Abstract: In magnetic recording media consisting of a nonmagnetic substrate and at least one magnetizable layer firmly applied thereon and based on magnetic material dispersed in a binder mixture which contains at least one hydroxyl-containing, preferably low molecular weight polyureaurethane and one polyurethaneurea (meth)acrylate, the polyurethaneurea (meth)acrylate is obtained by reacting a poly(meth)acrylate having up to 2 terminal OH groups per mol and a molecular weight of from 200 to 50,000 with a mixture of aliphatic polyisocyanates having an average functionality of from 3.0 to 6.0 NCO groups per mol, consisting of from 0.1 to 10% by weight of a diisocyanate, from 30 to 80% by weight of a triisocyanate and from 20 to 60% by weight of an isocyanate having a functionality of from 4 to 10, with the proviso that from 1.2 to 3.0 NCO groups react per OH group and the remaining NCO groups are converted into substituted terminal urea groups with a polyfunctional amine or with a mixture of different polyfunctional amines.
