Near-field light generator and thermally-assisted magnetic recording head
A near-field light generator includes a multilayer structure having a front end face. The multilayer structure includes a first dielectric layer, a second dielectric layer, a third dielectric layer, a first metal layer, and a second metal layer. The first metal layer is interposed between the first dielectric layer and the second dielectric layer. The second metal layer is interposed between the second dielectric layer and the third dielectric layer. Each of the first to third dielectric layers and the first and second metal layers has an end located in the front end face. The dielectric material used to form the first dielectric layer, the dielectric material used to form the second dielectric layer, and the dielectric material used to form the third dielectric layer have the same permittivity.
