Patent abstract
A high-density readable only optical disk with a large storage capacity includes a substrate with pits, and one or more mask layers with a super resolution near field structure, which are made of a mixture of a dielectric material and metal particles. The optical disk can be obtained without decreasing the wavelength of a laser diode or increasing the numerical aperture of an objective lens.
