A recording and/or reproducing apparatus (1) for a tape (12) in a cassette (2) includes a tape-guide device (24) for withdrawing the tape (12) from the cassette (2), wrapping the tape around a tape-guide drum (34) , and returning the tape into the cassette (2). The tape-guide device (24) includes a supporting ring (49) which is rotatable relative to the tape-guide drum (34), for carrying at least two tape guides (22,23), a first tape-guide (22) keeping the tape (12) wrapped around the tape-guide drum (34) and a second tape-guide (23) which in its operating position keeps the tape (12) away from the tape-guide drum (34). The second tape guide (23) is arranged on a lever (57) which is pivotable relative to the supporting ring (49) under the influence of the tape tension forces exerted on it, against the force of a spring (61) which acts on the lever (57), thus precluding looping of the tape and the occurrence of excessive tape-tension forces during change-over between search modes in different directions and when the tape is returned into the cassette (2).
