Description
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 15×7.5×5 nm^3 were arranged on a soft magnetic underlayer with an areal density of 2.6 Tdot/in^2. Saturation magnetization of each dot was assumed to be 1000 emu/cm^3. Media with three different inclination directions with an inclination angle of 30 degrees from the film normal were investigated for the recording performance using a shielded planar head field. It was found that the write shift margin in the cross track direction was increased for the medium with the inclination direction in the cross track direction. The cause of the increase was explained by the composite anisotropy of the dot elongated to the cross track direction with the shape anisotropy.
