| 英文摘要 | The present invention provides an electromagnetic field generating element, an information recording/reproducing head, and an information recording/reproducing apparatus. The electromagnetic field generating element makes it possible to restrain magnetic field attenuation or magnetic field delay in a high frequency recording/reproducing head for use in thermally assisted magnetic field recording/reproduction using a near field. The information recording/reproducing head and the information recording/reproducing apparatus can carry out high frequency magnetic recording/reproducing. The electromagnetic field generating element of the present invention includes: (i) a substrate, (ii) conductors each provided on the substrate and each serving as a supporting section, (iii) a plate-like-shaped conductor provided on the conductors and (iv) a semiconductor laser element provided on the substrate. The semiconductor laser element irradiated, to the plate-like-shaped conductor, laser light substantially parallel to an extending flat surface of the plate-like-shaped conductor. This causes generation of the near field in the plate-like-shaped conductor. Moreover, a magnetic field is generated by supplying a current to the plate-like-shaped conductor. |
