Hub compliance layer for reducing media stress

A product, comprising:

• a tape cartridge having:
• an outer housing;
• a tape spool positioned within the outer housing, wherein the tape spool includes:
• a first flange,
• a circular hub coupled to the first flange, and
• a cylindrical compliance layer which encircles the hub;
• and
• a magnetic tape wrapped around the compliance layer and the hub,
• wherein the compliance layer is configured to dampen radial stress exerted on inner wraps of the magnetic tape,
• wherein the compliance layer is directly coupled to an end of the magnetic tape and wound onto the hub, wherein the compliance layer is a laminate structure of uniform thickness, having more than one layer, wherein an inner surface of the compliance layer is directly coupled to an outer surface of the hub, wherein an adhesive material is present on an outer surface of the compliance layer,
• with a proviso that the tape spool does not have a second flange on an opposite side of the circular hub as the first flange.
