ABSTRACT:
An electromagnetic read/write head structure for longitudinal/horizontal reading and writing including first and second magnetic pole components which are spaced by a substantially uniform-width, linear, planar gap. Each pole component is characterized by a configuration, measured generally in the plane of the gap, where no portions of the outlines of the pole components, save those portions which actually define the gap, include any stretch extending parallel to the gap.
