Abstract

One of the factors affecting the performance of a magnetic recording head is the permeability of the yoke material which provides magnetic flux paths. Higher permeability produces greater efficiency. This article describes a set of fabrication parameters which maximizes the effective permeability of a thin-film laminated permalloy head.
