A system in which signals can be recorded on or reproduced from a magnetic tape in a cassette, the system comprising standard apparatuses and standard cassettes (29) which are adapted to each other in conformity with a specific standard, which standard cassettes can be positioned correctly on the standard apparatuses by at least one standard locating pin (41) which is engageable in a standard locating aperture (39) of the standard cassette. The standard system is a subsystem of a larger system which also includes deviating apparatuses (1) and deviating cassettes (3) which are adapted to one another in conformity with a deviating standard, which deviating apparatus comprises at least one deviating locating pin (21) which is engageable with clearance in a deviating locating aperture (35A, B) of a deviating cassette but also in a standard locating aperture (37A, B) of a standard cassette, but which deviating locating aperture (35A, B) has such a shape that the standard locating pin (41) is not engageable in the deviating standard aperture.
