ABSTRACT:
A device for guiding a magnetic tape suitable for being wound helically around a cylindrical drum and for running past at least one magnetic head driven in rotation around the periphery of a slot provided in an equatorial plane of the drum, the device being of the type comprising elongate bearing means linked to the drum and defining at least two bearing points against which one of the edges (bottom edge or top edge) of the tape may bear, the device including link means linking the bearing means to the drum and suitable for modifying the inclination of the bearing means as a function of temperature said link means suitable under the effect of differential thermal expansion to cause the bearing means to rotate about a radial axis (extending transversely to the axis of the drum) passing through a point which is invariant in rotation, and whose position is fixed regardless of temperature.
