摘要 |
A hard disk having an increased-density magnetic dot pattern, that prevents side erase. Provided is a storage medium comprising: a thin-layer magnetic body capable of generating and erasing skyrmions; a non-magnetic body provided so as to encircle the thin-layer magnetic body; and a magnetic field-generating unit facing a first surface of the magnetic body and being capable of applying a first magnetic field to the first surface of the magnetic body. The size of the flat surface of the thin-layer magnetic body fulfils 2λ > Wm > 0.5·λ and 2λ > hm > 0.5·λ relative to the diameter λ of the skyrmions generated by the thin-layer magnetic body, when the width of the flat surface is Wm and the height is hm. |
