An experimental study of rotary splitting of circular disk was conducted to survey the effect of forming parametars on the metal flow in rotary spritting. It was found that the radial force Fr increases with the increase in the initial blank thicknes

Bit patterned media with inclined anisotropy were proposed along with media design with a higher saturation magnetization and a small thickness for the dot. Inclination of the anisotropy axis was found to reduce broadened switching field distribution

Effect of inclination direction on the recording performance of bit-patterned media with weakly inclined anisotropy was investigated by simulation. Magnetic dots with a size of 15x7.5x5 nm3 were arranged on a soft magnetic underlayer with an areal de

SmCo 5 alloy is a promising candidate for ultra-high-density perpendicular magnetic recording (PMR) media because of its high uniaxial magnetocrystalline anisotropy K u of more than 1.1×10 8 erg/cm 3 . Previously, we successfully achieved high K u i

A simple technique for bit-patterned media was proposed to increase achievable areal recording densities beyond 2 Tbit/in 2 . Introduction of longitudinal magnetic anisotropy to the media indicated reduced effect of magnetostatic interaction between
