ABSTRACT:
In a laminated magnetic head core, Fe--M--N system soft magnetic thin films (M being at least one element selected from the group consisting of Ta, Nb, Zr, and Hf) and non-magnetic insulating films are alternately laminated. Each of the soft magnetic thin films is 0.2-10 .mu.m thick. Each of the non-magnetic insulating films is 10 through 1000 nm thick. One of the soft magnetic thin films shows high magnetic permeability in a different direction from that of an adjacent soft magnetic thin film via the non-magnetic insulating film within a film surface of the soft magnetic thin film.
