Abstract

A surface plasmon and magnetic field applicable synchronously hybridized (SMASH) head that generates magnetic field and surface plasmon at nanosized region is proposed. The capability of the SMASH head for the near-field assisted magnetic recording is demonstrated . The near-field assisted magnetic recording was performed with a spin-stand tester equipped with the SMASH head and the TbFeCo medium. The linear velocity was 0.9 m/s and the write current for the laser-assisted magnetic recording was 100 mA. An irradiating laser power for write process was 8 mW.
