摘要：
The object of the present invention is to provide an information recording/reproduction device for implementing high-density information recording and reading using mutual interaction of a recording medium with near field light, and particularly to a near field optical head with a high optical efficiency and a manufacturing method thereof. This is achieved by enabling an energy propagation mechanism via a plasmon by forming a layer dispersed with metal particulate at a microscopic opening generating near field light, and therefore increase optical efficiency.
