Abstract

A tape cassette, in particular a magnetic tape cassette, is provided, for tape and hub guidance, with bent support liners (7, 8) which are located between the roll (1) or rolls and the adjacent housing wall (6). According to the invention, bent-over or folded-over longitudinal strips (7a, 7b) which are bent at certain angles toward the housing wall (6) support the liners (7, 8) in such a way that it is possible to counteract deformation due to the weight of the rolls of tape. These liners (7, 8) can be used for all cassette recording media, but preferably for those having a very small tape thickness.
