Simulation of High Density Recording for Bit Patterned Media with Weakly Inclined Anisotropy Using Shielded Planar Head

Abstract (in Japanese) (See Japanese page) 
(in English) Recording properties of bit patterned media with 60-deg. weakly inclined anisotropy were studied by simulation. When a shielded planar head was used, a recording system with an areal density of 2.6 Tbit/in2 is expected with introduction of weakly inclined anisotropy. However, a small dispersion of less than 4 % in the anisotropy field and an orientation dispersion of less than 7 degree would be required. Possibility of a recording system with a density of 4 Tbit/in2 was also obtained when additional exchange coupling between the dots was introduced based on an extremely narrow distribution in the anisotropy field.
