Title (EN) NEAR-FIELD OPTICAL DEVICE, RECORDING DEVICE AND SAMPLE SUBSTRATE
(FR) DISPOSITIF OPTIQUE EN CHAMP PROCHE, DISPOSITIF D'ENREGISTREMENT ET SUBSTRAT D'ÉCHANTILLON
(JA) 近接場光デバイス、記録装置及びサンプル基板
Abstract: front page image
(EN)A near-field optical device (100) is provided with a quantum dots (113, 116) that generate near-field light on the basis of light emitted from outside, and an output end (118) that is capable of outputting at least some energy from the near-field light that is generated to the outside. The output end is formed in such a manner that the length in one direction, as viewed in a plane from above the output end, is longer than the length in another direction that intersects said one direction. The near-field optical device enables information to be appropriately recorded by heat-assisted magnetic recording.
(FR)L'invention concerne un dispositif optique en champ proche(100) pourvu de points quantiques (113, 116) qui génèrent une lumière en champ proche d'après la lumière émise depuis l'extérieur, et d'une extrémité de sortie (118) capable de générer au moins une certaine énergie à partir de la lumière en champ proche qui est générée vers l'extérieur. L'extrémité de sortie est formée de sorte que la longueur dans une direction, telle que visualisée dans un plan depuis le haut de l'extrémité de sortie, soit plus longue que la longueur dans une autre direction qui s'entrecroise avec ladite direction. Le dispositif optique en champ proche permet d'enregistrer les informations de façon appropriée au moyen d'un enregistrement magnétique assisté par chaleur.
(JA)近接場光デバイス(100)は、外部から照射される光に基づいて近接場光を発生する量子ドット(113、116)と、発生された近接場光のエネルギーの少なくとも一部を外部へ出力可能な出力端(118)と、を備える。出力端は、該出力端の上方から平面的に見て、一の方向に沿う長さが、該一の方向と交わる他の方向に沿う長さよりも長くなるように形成されている。当該近接場光デバイスによれば、熱アシスト磁気記録により情報を適切に記録することができる。
