| 摘要 |
The invention is a near-field optical head that generates near-field light to heat a predetermined area of a medium and applies a magnetic field to the predetermined area to record information, the head including an optical waveguide 103 having a path for propagating a pencil of light, and a tip 117 having an optical minute opening 118 at the position facing against the predetermined area and collecting the pencil of light emitted from the optical waveguide 103 and simultaneously propagating the collected pencil of light to the optical minute opening 118 to generate the near-field light. The optical minute opening 118 is formed by a magnetic pole that applies a magnetic field to the predetermined area.
