Abstract

A thin-film magnetic head includes a magnetoresistive element, a shielding layer, and an insulating layer disposed between the magnetoresistive element and the shielding layer. The shielding layer is composed of an amorphous material and the surface thereof facing the magnetoresistive element is covered by a crystallization-inhibiting film for inhibiting crystallization of the shielding layer. The crystallization-inhibiting film may have an antioxidizing function for the shielding layer.
