| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Thermally assisted magnetic recording is one of the possible candidates that achieves the areal densities of 1 terabit/inch2. In the scheme, the recording layer is heated by the external, optical energy. The signal is recorded when the coercive force of recording layer is reduced, therefore, relatively small magnetic field is necessary to switch the medium. In this report, the optical near fields from the metallic, thin film have been obtained for various structures with and without the aperture by using the three-dimensional finite-difference time-domain (FD-TD) method. Finally, the head field and the near field energy distributions are compared and discussed if a proper thermal energy can be applied to the recording layer. |
