Abstract
A near-field optical disk having surface plasmon amplification by stimulated emission of radiation (SPASER) is provided. The near-field optical disk having SPASER includes a transparent substrate, a first transparent dielectric thin film layer formed on the transparent substrate, a SPASER thin film layer formed on the first transparent dielectric thin film layer, a second transparent dielectric thin film layer formed on the SPASER thin film layer, a recording thin film layer formed on the second transparent dielectric thin film layer, and a third transparent dielectric thin film layer formed on the recording thin film layer.
