N2 - This investigation relates to magnetic transducing apparatus (magnetic tape units and potentially magnetic disk units) for use in read-while-write (RWW) mode. We shall confine ourselves here to the most important part of the noise, that resulting from field interaction. This type of coupling is called “crossfeed” noise and it is caused by radiation across the recording surface of the magnetic transducer head due to the electromagnetic field. As a result, a favoured scheme to suppress the crossfeed noise from the write head in a RWW head is to employ a dual-MR sensor instead of a conventional SAL MR sensor. The measured signal-crossfeed ratio (SCR) agrees reasonably with the theoretical predictions
