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.

摘要： A super-resolution information storage medium having recording marks or pits that are smaller than the resolution limit of a beam incident from an information recording and/or reproducing apparatus, and the information recording and/or reproducing apparatus. The information storage medium includes a substrate and at least one super-resolution reproduction layer containing a super-resolution material and a high melting point material with a melting point higher than that of the super-resolution material formed on the substrate. The high melting point material suppresses movement of the super-resolution material in a melted phase so as to prevent signal degradation caused by repeated reproduction.

摘要： A high density readable only optical disc includes a substrate having pits with different lengths in accordance with unit information, wherein a depth of the pit increases as the pit length increases; and a mask layer that includes a metal oxide, or a mixture of fine metal particles and a dielectric material. The high density readable only optical disc may be used to read pits not greater than a reading resolution limit and to obtain an optimal CNR since a pit depth is varied depending on a pit length. Also, a method of the high density readable only optical disc may be used to prepare a high density readable only optical disc having an optimal pit depth in accordance with a pit length.
