Abstract: A magnetic tape guidance device, which may be in the form of a cartridge, for use with a record/playback machine, so that the tape is drawn past record/playback heads on the machine by drive means also provided on the machine. The device includes a precision guide post which guides tape towards the record/playback heads and the drive means, and a flat second guide at right angles to the axis of the cylindrical guide post which maintains the height of the tape correctly in relation to the record/playback heads, the device also including a tape tensioning device which applies frictional resistance to the tape prior to movement around the guide post such that wrap of the tape around the guidepost is symmetrical.
