摘要： The present invention provides an optical recording medium in which the spot size of incident laser beam, focused on the medium by a far-field optic system characterized by λ and NA, is further reduced and maintained below the diffraction-limited size by means of material characteristics of the medium while reproducing from and recording on the information layer of the recording medium, thus making it possible to record and reproduce a high density of information exceeding the resolution limit of the optic system.A high density optical recording medium according to the present invention adopts a combination of two different super-resolution layers of mutually complementary optical characteristics with increasing light power.The combination of two super-resolution layers is made in either of two different types: for one type, each of the two super-resolution layers, having a respective threshold light intensity (or temperature) for the onset of change in optical transmittance, produces an increasing spot size of the transmitted beam with increasing light power once a respective threshold light intensity (or temperature) is exceeded, and for the other type, one layer produces an increasing spot size of the transmitted beam with increasing light power whereas the other layer exhibits a reverse trend.
摘要翻译：本发明提供了一种光记录介质，其中通过以λ和NA为特征的远场光学系统聚焦在介质上的入射激光束的光斑尺寸进一步减小并通过材料保持在衍射受限尺寸以下在从记录介质的信息层再现和记录介质的同时，能够记录和再现超过光学系统的分辨率极限的高密度信息。根据本发明的高密度光学记录介质采用具有增加的光功率的互补光学特性的两个不同的超分辨率层的组合。两个超分辨率层的组合以两种不同类型中的任一种制成：对于一种类型，两个超分辨率层中的每一个具有用于光透射率变化开始的相应的阈值光强度（或温度），产生一旦超过相应的阈值光强度（或温度），一旦增加了光功率，透射光束的斑点尺寸就会增加，而另一种类型，一层产生随着光功率的增加的透射光束的光斑尺寸，而另一层呈现逆向趋势。

摘要： The present invention is related to a super-resolution composite material for a high density optical information recording medium which consists of a dielectric medium that is transparent at a laser wavelength in use and has a melting point higher than 800° C., and metal particles that are dispersed in the dielectric medium and have low melting points of 150˜450° C. Super-resolution capability of the material is rendered by metal particles that undergo reversible phase changes between melt and crystalline states, accompanied by changes in optical properties. As the dielectric medium, at least one material is selected for use from the group of SiO2, TiO2, ZrO2, HfO2, Al2O3, ZnO, Y2O3, BeO, MgO, WO3, V2O3, SiN, AlN, ZnS, CdS SiC, MgF, CaF2, NaF, BaF2, PbF2, LiF, LaF3, GaP. As the metal particles with low melting points and high boiling points, at least one material is selected for use from a group of Sn, Pb, Bi, Te, Zn Cd, Se, Tl and Po.
