Abstract
Thin film magnetic head has magnetoresistive element (,) and flux-guiding elements (,) of a material having a relatively high magnetic permeability, and an intermediate layer between the magnetoresistive element and the flux-guiding elements, the intermediate layer (,) being electrically insulating, and having a relatively low magnetic permeability of between 1.1 and 25. The low permeability intermediate layer increases the magnetic flux between the magnetoresistive element and the flux-guiding elements, and thereby improves the efficiency of the magnetic head.
