MEDIUM FOR MAGNETIC RECORDING ON MAGNETIC NANOSTRUCTURES Russian patent published in 2010 - IPC G11B5/84 B82B1/00 

FIELD: physics.

SUBSTANCE: medium for magnetic recording contains a ferromagnetic film placed on a substrate with a profiled surface which forms a periodic two-dimensional nanostructure from single nanosized elements. The ferromagnetic film covers the nanostructure from single nanosized elements with a continuous layer on their bases, lateral slopes and the bottom of the profile and has a stripe domain structure. Parametres of the stripe domain structure of the ferromagnetic film and the nanostructure satisfy the condition: T₁=(0.95-1.05)T₂, where T₁ is the period of the stripe domain structure of the ferromagnetic film, T₂ is the period of the nanostructure.

EFFECT: increased remnant magnetisation and coercitivity of the ferromagnetic film.
