    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： An information storage medium reduces low frequency noise, and an apparatus records and/or reproduces information thereon. The information storage medium includes a substrate; a recording layer formed on the substrate and including at least two materials in which the materials chemically react with each other due to an incident beam thereon having a write power and form a recording mark; and a super resolution reproduction layer formed on and/or under the recording layer and having a property in which optical characteristics of a partial area of a spot due to the incident beam are changed. The apparatus to record and/or reproduce information on the information storage medium includes a pickup unit having a light source, an objective lens to form a beam spot on the information storage medium, and a photodetector; a signal processor; and a controller.

    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.

    摘要： A super-resolution information storage medium and a method and apparatus for recording and/or reproducing data to and/or from the same, the super-resolution information storage medium designed to allow reproduction of information recording marks smaller than a resolution limit of an incident beam and includes a substrate, a recording layer formed on the substrate and having recording marks formed due to thermal decomposition at a portion on which the incident beam is focused, and a super-resolution layer formed on the recording layer using a material having a melting point lower than the thermal decomposition temperature of the recording layer. The super-resolution information storage medium has a super-resolution layer made of a material having a melting point lower than the thermal decomposition temperature of the recording layer so that the recording layer is not adversely affected due to repeated irradiation with a readout beam, thereby providing improved readout performance.
