Abstract
Rotary scanner apparatus includes a headwheel having at least one magnetic head arranged for making successive operative sweeps across a magnetic tape. To achieve high data rate transfer, a unitary microwave transmission link includes a fixed cylindrical waveguide on a stationary side of the head scanner and a cooperating cylindrical waveguide rotatably mounted on the rotating side of the scanner. The waveguides are coaxially arranged along the rotational axis of the headwheel for directing a microwave signal, corresponding to a high data rate signal, to and from the headwheel during recording and playback operations. When the headwheel carries multiple magnetic heads, the unitary transmission link serves advantageously for the simultaneously coupling of a recording signal and a playback signal to and from the head scanner, for testing and certifying a recording system in real time.
