ABSTRACT:
A composite magnetic head has a media-contact surface defined by a gapped magnetic core sandwiched between a pair of ceramic substrates. The core is laminated and comprises thin layers of sputter-deposited FeRuGaSiX uniaxial anisotropic magnetic material alternating with even thinner layers of a dielectric material, where X is selected from the group consisting of Zr, Re, Ni and Co.
