Abstract
This paper reviews the research done on soft-magnetic fluxguide materi als for use in sandwich heads and in thin-him recording heads for digi tal magnetic recording. After dealing with the basic principles of mag netic recording, the requirements on modern soft-magnetic materials ar e discussed. The roles of magnetic anistropy and magnetostriction in r elation to permeability are discussed. Next, we review the recent adva nces in soft-magnetic materials processing, in particular for amorphou s cobalt (Co-Nb-Zr) and nanocrystalline iron alloys, such as Fe-M-X, w ith M being group IVa-Va metals such as Zr, Hf, Nb, Ta, etc., and X be ing N and O.
