摘要： In the conventional super-resolution reproduction method, an optical spot size is changed by power of the laser beam applied to an optical disc and accordingly, it is necessary to decide an optimal laser power for super-resolution reproduction for each of the recording pattern sizes. The present invention provides an optical disc formed by a recording layer and a material layer having changing viscosity. When a laser beam is applied for reproducing information recorded in the recording layer, a part of a crystalline thin film of the material layer having changing viscosity is softened. The optical constant of the softened part is changed and a discontinuous plane of the optical constant is generated at the boundary of the softened part so as to form a ring-shaped peculiar region in the optical spot. By this ring-shaped peculiar region, it is possible to reproduce a recording pattern of size smaller than the resolution limit with a signal intensity equivalent to the recording pattern of a greater size.

摘要： A simple-structured recording medium without a mask layer and information recording and reproducing methods, which resolve thermal stability related problems arising during reproduction, the recording medium including a high melting point recording layer between first and second dielectric layers. The method of recording information on the recording medium involves irradiating a laser beam onto the recording medium to induce reaction and diffusion in the high melting point recording layer and the first and second dielectric layers. The method of reproducing information recorded on such a super-resolution near-field recording medium by the above method involves generating plasmon using crystalline particles of the high melting point recording layer and the first and second dielectric layers as a scatter source to reproduce information regardless of a diffraction limit of a laser used.

摘要： A data reproducing method reproducing data recorded in a super resolution information storage medium in a form of marks having magnitudes less than a resolving power of an incident light beam, and an apparatus thereof. The data reproducing method includes irradiating a first beam having a resolving power causing a super resolution phenomenon and a second beam having a resolving power not causing a super resolution phenomenon into different places on the information storage medium, detecting a first reproduction signal based on the first beam and a second reproduction signal based on the second beam, and compensating for and calculating a temporal delay between the first reproduction signal and the second reproduction signal. Therefore, a signal reflected from a peripheral area of a reproduction beam spot other than a super resolution area can be excluded, thereby improving reproduction signal characteristics.
