<p>A recording head having magnetic poles with a high saturated magnetic flux density, a high permeability, and a high electrical resistivity. The poles are polycrystalline films containing 57.5 to 94.5 atomic percent of Fe, 1 to 15 atomic percent of one or more elements selected from the group consisting of Al, B, Ga, Si, Ge, Y, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, and Rh, 0.5 to 10 atomic percent of N, and 1.5 to 22.5 atomic percent of O.</p> |
