ABSTRACT:
A recording head having a plurality of recording electrodes and at least one return circuit electrode. The recording head further includes an insulating layer consisting of an integrated mica, which is disposed between an array of the plurality of recording electrodes and the return circuit electrode, so as to form a multi-layer structure which includes the recording and return circuit electrodes, and the insulating layer. The recording and return circuit electrodes are formed of an electrically conductive material which has a higher degree of wear resistance than that of the integrated mica.
