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 1µ 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.\u003c\/p\u003e \u003ch3\u003eDetails\u003c\/h3\u003e \u003cp\u003ePublished by: Springer\u003c\/p\u003e \u003cp\u003ePublication Date: 2004-10-04\u003c\/p\u003e \u003cp\u003eFormat: Hardcover\u003c\/p\u003e \u003cp\u003eISBN-13: 9783540210504\u003c\/p\u003e \u003cp\u003eDOI: 10.1007\/b138176\u003c\/p\u003e \u003cp\u003eDimensions: 235cm x155cm\u003c\/p\u003e \u003cp\u003ePages: 224\u003c\/p\u003e ","brand":"Springer Berlin Heidelberg","offers":[{"title":"Default Title","offer_id":45578351050892,"sku":"9783540210504","price":152.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/9545\/1788\/files\/9783540210504.jpg?v=1774026814","url":"https:\/\/lateknightbooks.com\/products\/9783540210504","provider":"Late Knight Books and Services, LLC","version":"1.0","type":"link"}
