ABSTRACT:
A magnetic-tape apparatus (1) having a capstan (33) and a pressure-roller device (47) which includes a pressure roller (29) which can be pressed against the capstan (33) and which is rotatably supported on a pressure-roller spindle (50) by a bearing member (51). An outer bearing surface (56) of the bearing member (51) is formed by an outer toric surface having a given meridian radius and an inner bearing surface (55) associated with the pressure roller (29), which inner bearing surface cooperates with the outer bearing surface (56) of the bearing member (51), is formed by an inner toric surface having a given meridian radius, and the outer toric surface (55) associated with the pressure roller (29).
