摘要： An improvement in production of an optical recording medium of phase change type is provided. In the present method, the step of repeated recording and erasing which had to be carried out after initialization and before shipment in the conventional process is eliminated. The optical recording medium produced by the present process retain good properties after repeated overwriting. In the process of the present invention, the prior art initialization step is replaced by modification treatment and the subsequent crystallization treatment. The modification treatment is a step wherein non-crystalline recording layer formed by sputtering is melted and cooled to change the crystal-lographic state into a non-crystalline state which is different from the non-crystalline state immediately after the formation of the recording layer. The crystallization treatment is a step conducted after the modification treatment wherein the recording layer in non-crystalline state is heated for crystallization.

摘要： In an optical information medium having an information bearing surface having projections and depressions and/or capable of forming recorded marks, a functional layer is added. The information borne on the information bearing surface can be read by using reading light of a wavelength longer than 4NA·PL wherein PL is the minimum size of the projections and depressions or the recorded marks and NA is the numerical aperture of a reading optical system, setting the power of the reading light within such a range that the functional layer does not change its complex index of refraction, and irradiating the reading light to the information bearing surface constructed by the functional layer or to the information bearing surface through the functional layer or to the functional layer through the information bearing surface. The medium enables reading at a high resolution beyond the diffraction limit.
