Abstract
A guide device for tape-like recording media, especially a reversing guide device for magnetic tapes, that are transported at high speed, which comprises at least one guide roll, around whose periphery the recording medium is guided, and which is rotatably mounted in bearings, a deliberate specific braking torque being produced between the guide roll and its bearings. Further embodiments concern the roughness of the roll's peripheral surface, the design of flanges for the lateral guidance of the recording medium and the use of two guide rolls. The braking torque is produced by braking means acting on the guide roll. The novel guide device can be used advantageously in any high-speed magnetic tape transport apparatus for the recording/reproduction of any type of audio, video or data signal.
