Fabrication and Recording Properties of Shielded Planar Type Single Pole Write Head

We fabricated a shielded planar single-pole write head that combined a tapered main pole to obtain a strong write head field and a wraparound shield to obtain a steep head-field distribution. Anisotropy etching pits of Si were used as a template to fabricate the new head, and magnetic yoke material was embedded in the template to form the tapered main-pole tip. As a result, this new head could be fabricated using a novel technique that is different from that used for present recording heads. Our first test recording with the head was successful.
