Influence of trailing shield size on oscillating characteristics of STO

Abstract (in Japanese) (See Japanese page) 
(in English) Microwave-assisted magnetic recording (MAMR) has been proposed as a promising technique to achieve a higher areal recording density over 1.0 Tbit/inch2. MAMR requires a spin-torque oscillator (STO) to generate a strong, high-frequency magnetic field to induce magnetic resonance in a recording medium. The oscillating characteristics of STOs were previously investigated using calculation model witch neglected the magnetic interactions between the STO and an SPT writing head. Thus we developed a new simulator that combines an SPT head and an STO simulators, called an integrated MAMR simulator. The simulator revealed that trailing shield height considerably influences the oscillating characteristics of STO due to the change of the gap field strength between the trailing shield and main pole.
