Abstract: Head wherein an axis of easy magnetization in the vicinity of a magnetic gap (g) of a magnetic yoke (37) is forcibly made coincident with the direction of a track width by a magnetic field due to current flowing in a conductor layer (1). Accordingly, even though the track width is small, a high magnetic permeability, low Barkhausen noise and linear responsiveness can be realized to thereby improve the sensitivity, output and linearity. In another aspect of the invention, a throat portion is eliminated from a thin film magnetic core forming a magnetic gap. The thin film magnetic core is configured such that a pair of magnetic members constituting the magnetic core are diverged from the magnetic gap so that a divergent angle theta , of first opposite side edges of the magnetic members, from a direction of the gap length of the magnetic gap, is set to the range of 30 DEG
