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.
Claims13
In a magnetic head comprising at least one head element, which head element comprises a core in the form of a ring and at least one magnetic coil, which core is composed of a magnetic core body discontinuous at at least one gap extending from the outer peripheral to the inner peripheral surfaces of the ring shaped core and a spacer inserted into each said gap, a coil, a magnetic flux being applied from the coil received by the coil from a part of magnetic recording medium in contact with the discontinuous part of said core body at said one gap, the improvement comprising employing as said core body a metal which is at least a 50% amorphous metal alloy.
