Abstract (in Japanese) (See Japanese page) 
(in English) In this work we optimise dual-structure media for microwave-assisted magnetic recording. The recording medium consisted of two, discrete exchange-coupled composite recording structures, each with hard and soft magnetic layers. The magnetic properties of the hard and soft layers of each ECC structure were optimised using response surface methodology. Optimisation parameters included: hard and soft layer uniaxial anisotropy, the strength of exchange coupling between the hard and soft layers and the frequency of the spin torque oscillator (STO). Next, the ADC was calculated for a range of STO widths, using the written track width and signal to noise ratio (SNR) of written tracks as inputs. A grain switching probability model was used to understand the factors that influence recording performance.end{eabstract}
