In this chapter, we focused on the near-?eld optical head, which is a key device for near-?eld optical recording. First, we explained the technical issues regarding the near-?eld optical head and introduced some solutions to these issues. We focused on a highly e?cient near-?eld optical head that uses a wedge-shaped metallic plate, and described its optical pr- erties based on a simulation using a ?nite-di?erence time-domain method. The simulation results con?rmed that a strong optical near ?eld is generated at the apex of the metallic plate when a plasmon is excited in the metallic plate. When a TbFeCo recording medium was placed 10 nm from the ne- ?eld optical head, the size of the optical spot was 30 nm, which corresponds 2 to an areal recording density of approximately 1 Tb\/in . The e?ciency was 20% if we assume that the incident beam was a Gaussian beam with a full width at half-maximum of 1  m. Furthermore, we discussed an optical head using two metallic plates. We con?rmed through our simulation that a highly localized optical near ?eld was generated at the gap when the plasmon was excited in the metallic plates. The distribution was 5 nm by 5 nm when the two apices were separated by 5 nm.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Motoichi Ohtsu\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 3540210504\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9783540210504\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Springer\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 10\/04\/2004\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 224\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Hardcover\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 1.10lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.20h x 6.30w x 0.70d","brand":"Motoichi Ohtsu","offers":[{"title":"Hardcover","offer_id":47579925840127,"sku":"9783540210504","price":169.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_143f3ae9-cd17-4266-bb41-28f993d14d40.jpg?v=1763877617","url":"https:\/\/www.whiterainbookhouse.com\/products\/progress-in-nano-electro-optics-iii-motoichi-ohtsu-9783540210504","provider":"WR Book House","version":"1.0","type":"link"}
