Near-field light generator plate, thermally assisted magnetic head, head gimbal assembly, and hard disk drive |
摘要 |
A near-field light generator plate 36 of the present invention is arranged to face a medium 10, and one portion 36b and other portion 36a in a medium-facing surface S thereof are made of their respective electroconductive materials different from each other. Since the one portion and the other portion in the medium-facing surface are made of the electroconductive materials different from each other, this medium-facing surface is formed by a surface removing step such as polishing or etching from the medium-facing surface side so that a difference between heights of the one portion and the other portion is readily made based on the difference of the materials.
