PCT No. PCT/JP95/01667 Sec. 371 Date Feb. 20, 1998 Sec. 102(e) Date Feb. 20, 1998 PCT Filed Aug. 23, 1995 PCT Pub. No. WO97/08687 PCT Pub. Date Mar. 6, 1997A leaking magnetic flux from a taper portion is canceled by utilizing an eddy current loss by using a magnetic head having a structure wherein at least a part of a magnetic pole constituting a magnetic path through a recording gap is sandwiched by conductive materials with respect to a track width direction, and a write blur quantity can be thus reduced. Further, magnetic saturation can be prevented by limiting a volume decrease at the distal end portion of the magnetic pole when the track width is reduced. Accordingly, the present invention can prevent magnetic saturation of the distal end portion of the magnetic pole resulting from the reduction of the width of the track of the recording head, can accomplish narrow-track recording by the recording head to a recording medium having high-coercive force and can reduce write blur. Further, the present invention can provide a narrow-track magnetic head capable of accomplishing a high-speed transfer, large-capacity magnetic recording system, and a magnetic memory apparatus using this magnetic head.
