Abstract

This paper reviews the research done on soft-magnetic fluxguide materials for use in sandwich heads and in thin-film recording heads for digital magnetic recording. After dealing with the basic principles of magnetic recording, the requirements on modern soft-magnetic materials are discussed. The roles of magnetic anistropy and magnetostriction in relation to permeability are discussed. Next, we review the recent advances in soft-magnetic materials processing, in particular for amorphous cobalt (Co-Nb-Zr) and nanocrystalline iron alloys, such as Fe-M-X, with M being group IVa-Va metals such as Zr, Hf, Nb, Ta, etc., and X being N and O.
