Abstract
A magneto-resistive head includes a stabilizing bias layer which applies a magnetization stabilizing bias field on a magneto-resistive layer of a magneto-resistive element, and a ferromagnetic underlayer which forms an underlayer with respect to the stabilizing bias layer. The ferromagnetic underlayer is made of Fe and has a film thickness in a range of 1.3 to 2.5 nm.
