摘要：
A thermally assisted magnetic recording head is formed of a slider and a magnetic head. The magnetic head includes a main pole, a reader, a coil, a near-field transducer, and a waveguide. A metal film with high thermal conductivity is formed at both sides of the near-field transducer in a width direction of the magnetic head. The use of the metal film as a radiator plate ensures to prevent the temperature of the near-field transducer from becoming locally high.
