ABSTRACT:
In a tape scanning device for magnetic tape equipment of the kind used for recording and/or reproducing broad band signals, by designing the head wheel carrying the rotating magnetic heads as a tachometer disc or drum, substantial advantages are obtained when replacement of the head wheel is required due to damage or wear, in particular the avoidance of the need to achieve precise correspondence of the angular positions of the head wheel and tacho disc during reassembly.
