Such devices include a stationary hollow guide drum having two parts spaced apart to define a slot with the drum being adapted to receive a magnetic tape engaging less than 360.degree. of the periphery thereof and a head-wheel carrying at least two magnetic heads and disposed in the drum for the rotation of the magnetic heads transversally to the slot for scanning the magnetic tape which is moved diagonally across the slot. The improvement includes a guide drum holder having two parts and operable for retaining the parts of the guide drum in a predetermined alignment, first connecting means operable to connect rigidly each part of the holder means to respective parts of the guide drum, and second connecting means operable to connect detachably the parts of the holder means to each other, whereby the holder can be disconnected and then connected and the parts of the guide drum will be substantially in the predetermined alignment.
