In the case of a magnetic-tape apparatus (1) and/or in the case of a pressure-roller unit (65), a pressure-roller spindle (55) and a bearing part (60), which surrounds the pressure-roller spindle (55) and can be rotated relative to the pressure-roller spindle (55), for rotatably bearing a pressure roller (29) are provided, the bearing part (60) having a first bearing surface (63) which is formed by a toroidal surface and cooperates with a second bearing surface (64) likewise formed by a toroidal surface, the two bearing surfaces (63, 64) formed in each case by a toroidal surface permitting a wobbling movement of the pressure roller (29), and the two bearing surfaces (63, 64) being held lying against one another without play, and of these two bearing surfaces (63, 64) at least one bearing surface (63) being provided in a compliant fashion in radial directions relative to the other bearing surface (64). |
