A rotating transducing head drum, upon each revolution, carries of plurality N>3 of peripherally mounted transducer heads in K>2 successive sets each of P>1 successive sweeps across the surface of a record medium; a plurality of at least P rotating transformer halves is coupled to said heads, each head in a set to a different transformer half; and a plurality P of stationary transformer halves is provided to transmit and receive signals from the rotating halves. The number of rotating transformer halves can be as great as N, but still only P stationary halves are required.
