Abstract

PURPOSE:To achieve the improvement in erase characteristics by alternately laminating amorphous alloy layers and permanent magnet layers in such a manner that their interfaces mate with a recording medium and magnetizing a first magnetic pole on the mating face side of the magnetic layers and a second magnetic pole on the opposite side.
