抄録

A novel single pole head with laminated thin film coils is proposed in this paper. Laminated thin film coils, between which a main pole is laid, are put very close to the media to capture most of the reproduced flux. In addition, a ferrite return yoke is placed just under the lower conductor to shorten the head magnetic flux path. These approaches bring high read/write efficiency and small head noise owing to low head impedance. With only one or two-turn coils, Co-Cr/Fe-Ni-Nb double-layered media were saturated at magneto-motive force of 0.05 ampere-turn, and overwrite of the two-turn head reached 35 dB. High normalized output of 1000 nVp-p/µm · turn · m/s was obtained. Much higher recording and reproducing sensitivity than ordinary inductive single pole heads was achieved.
