Abstract
Amorphous metal alloys are employed in a magnetic head as core materials in the present invention. Such alloys are generally composed of M and Y, wherein M is at least one of Fe, Ni and Co and Y is at least one of P, B, C and Si. The amorphous metal alloys used are marked by a combination of the desirable properties of conventional permalloy with those of conventional ferrites.
