    摘要： An object of the invention is to provide an optical-recording medium in which problems such as cross-write, i.e., signals are recorded wrongly on adjacent tracks, and cross-erase i.e., recording signals on adjacent tracks are erased wrongly, can be solved, and which enables high-density recording; a method for producing the optical-recording medium; and a method for recording and reproducing an optical-recording medium. To achieve this object, the optical-recording medium includes a substrate, an optical-absorption layer which absorbs light and generates heat on or above the substrate, a recording layer, and record-blocking portions which block recording on the recording layer, in which the record-blocking portions are disposed between the recording layer and the optical-absorption layer, and between adjacent tracks, and recording marks are formed on the recording layer by the optical absorption function of the optical-absorption layer.
