摘要： A write-once high density optical recording medium capable of a high speed recording that effectively forms space between recording marks. A recording layer 18 of a high speed write-once optical recording medium 10 is formed by laminating a first sub recording layer 18A and a second sub recording layer 18B each containing a metal as its main component. When the recording layer (laminated recording layer) 18 is irradiated with a laser beam, the main component metals contained in the first and second sub recording layers 18A, 18B diffuse and are mixed together by means of the irradiation, thereby forming recording marks whose reflectance have been irreversibly changed due to such mixing. At this time, after an irradiation using a laser beam for forming recording marks, a power level P1 lower than a read power is maintained for a predetermined time Ti.

摘要： A method of manufacturing a multilayer optical recording medium fabricates a first stamper made of metal and a resin stamper in which a fine protrusion/depression pattern is formed, the fine protrusion/depression pattern of the resin stamper being formed by transferring a pattern from a metal stamper, being deeper than a reversed fine protrusion/depression pattern of the first stamper, and being capable of forming, in one surface of a spacer layer, guide grooves of equal depth to guide grooves formed in one surface of a substrate. By transferring a pattern from the first stamper, the substrate that has guide grooves formed in one surface is fabricated. A recording layer is formed on a surface of the guide grooves of the substrate and a light transmitting resin is applied onto the surface of the recording layer. A pattern is transferred from the resin stamper to the surface of the light transmitting resin to form the spacer layer in which guide grooves of equal depth to the guide grooves formed in the substrate are formed, and the recording layer is formed on the surface of the guide grooves of the spacer layer.

The optical recording medium has a recording layer 4 comprising at least one phase change layer 41 and at least one functional layer 42 in contact with the phase change layer. The component constituting the phase change layer 41 and the component constituting the functional layer 42 undergoes a reaction to produce a reaction product when the phase change layer 41 is heated to a temperature equal to or higher than the melting point of the phase change layer 41, and the area where the reaction product has formed experiences decrease in its optical reflectivity, and the optical reflectivity after such decrease is maintained even if the area wherein the reaction product has formed is heated to the crystallization temperature of the phase change layer.
