Optical information recording medium and player thereof

Abstract

Abstract PURPOSE:To allow recording and reproducing of information at a high density by disposing island-shaped light emitting areas which emit light of the wavelength different from the wavelength of irradiating light by sensing the irradiating light between a transparent substrate and a reflecting layer and recording the information by the arrangement thereof. CONSTITUTION:Arrays of very small recesses 12 are provided on one main plane of a substrate 11 which is the transparent substrate and the island-shaped light emitting areas 13 are constituted by packing as light emitting material which emits the light of the wavelength different from the wavelength of the irradiating light by sensing the irradiating light from the other main surface side of the substrate 11 into these recesses. The reflecting layer 14 is provided to the outer side of the light emitting areas 13. The reflecting layer 14 reflects the irradiating light from the other main surface side of the substrate 11 and the light emitted in the light emitting areas 13, respectively. The information is, therefore, recorded by the arrangement of the island-shaped light emitting areas 13 formed by the recesses 12. The recording and reproducing of the high- density information are possible in this way.
