ABSTRACT:
A magnetic-tape-cassette apparatus (1) includes a head-mounting plate (10) and a magnetic head (3) arranged on the head-nounting plate (10) and having a cylindrical tape-contact face (12) and an air gap (25). The magnetic head (13) forms part of a head unit comprising a head support (16) which, viewed in the direction of tape transport, includes a tape guide (18) before and after the magnetic head (13), which tape guide has cylindrically curved guide surfaces (21) which at one side are bounded by alignment surfaces (23) at one of their axial ends. Each of the guide surfaces (21) is adjoined by a control edge (24) which is inclined relative to the guide surface (21) to urge the magnetic tape against the relevant alignment surface (23) during tape transport, the axial length of the guide surfaces (21) being smaller than or equal to the tape width (b). At a distance fromthe guide surface (21) each control edge (24) of the head support (16) changes to a movement-limiting surface (26), the distance between the facing alignment surface (23) and movement-limiting surfaces (26), starting from the transition (27), being greater than the tape width (b) in such a way that as the magnetic tape (11') is lifted off the guide surfaces (21) while the magnetic tape remains in contact with the tape-contact face (12) of the head (13) the position of the magnetic tape (11') in the direction of its width (22) is limited with play, said distance increasing from the centre of the relevant movement-limiting surface (26) towards its lateral edges (26a, 26b).
