<P>PROBLEM TO BE SOLVED: To provide an information recording head, an information recording device, and an information recording method, realizing high-speed recording and high-density recording simultaneously in information recording by means of direct magnetization reversal by circular polarization. <P>SOLUTION: A plasmon antenna 22 having a rotationally symmetrical opening 22A having a shape that is roughly rotationally symmetrical around an axis in the direction of progress of recording light radiated at a nanometer size that is larger than bit carriers 15 on bit patterned media 10 is irradiated with femtosecond pulse laser light as the above-described recording light, and is excited by the femtosecond pulse laser light radiated as the recording light at the plasmon antenna 22, and by means of interaction of the bit carrier 15 on the bit patterned media 10 positioned facing the rotationally symmetrical opening 22A of the plasmon antenna 22 and the rotationally symmetrical opening 22A of the plasmon antenna 22, circularly polarized light is generated within the bit carrier 15 and information is recorded by means of direct magnetization reversal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
