Patent ID: 8324696

Claim:
A magnetic recording element comprising: a read electrode; a magnetic pinned layer formed on the read electrode; an insulating layer formed on the magnetic pinned layer; a magnetic free layer formed on the insulating layer, in which a magnetic vortex is formed; and a plurality of drive electrode pairs disposed to form an ohmic contact with the magnetic free layer to apply a current of which a direction varies clockwise or counterclockwise with time in order to rotate the core orientation of the magnetic vortex, wherein the plurality of drive electrode pairs comprise two drive electrode pairs, and four drive electrodes forming the two drive electrode pairs are shaped in a plate extending in a direction and are formed at intervals of 90° in a circumferential direction of the magnetic free layer, wherein two drive electrodes of the four drive electrodes facing each other form one drive electrode pair, and the other two drive electrodes of the four drive electrodes facing each other form another drive electrode pair.
